phpinfo

(PHP 4, PHP 5, PHP 7, PHP 8)

phpinfo — Outputs information about PHP's configuration

Description

phpinfo(int $flags = INFO_ALL): true

Outputs a large amount of information about the current state of PHP. This includes information about PHP compilation options and extensions, the PHP version, server information and environment (if compiled as a module), the PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers, and the PHP License.

Because every system is setup differently, phpinfo() is commonly used to check configuration settings and for available predefined variables on a given system.

phpinfo() is also a valuable debugging tool as it contains all EGPCS (Environment, GET, POST, Cookie, Server) data.

Parameters

flags

The output may be customized by passing one or more of the following constants bitwise values summed together in the optional flags parameter. One can also combine the respective constants or bitwise values together with the bitwise or operator.

**phpinfo()** options
Name (constant)	Value	Description
INFO_GENERAL	1	The configuration line, `php.ini` location, build date, Web Server, System and more.
INFO_CREDITS	2	PHP Credits. See also phpcredits().
INFO_CONFIGURATION	4	Current Local and Master values for PHP directives. See also ini_get().
INFO_MODULES	8	Loaded modules and their respective settings. See also get_loaded_extensions().
INFO_ENVIRONMENT	16	Environment Variable information that's also available in `$_ENV`.
INFO_VARIABLES	32	Shows all predefined variables from EGPCS (Environment, GET, POST, Cookie, Server).
INFO_LICENSE	64	PHP License information. See also the » license FAQ.
INFO_ALL	-1	Shows all of the above.

Return Values

Always returns true.

Examples

Example #1 phpinfo() Example

<?php

// Show all information, defaults to INFO_ALL
phpinfo();

// Show just the module information.
// phpinfo(8) yields identical results.
phpinfo(INFO_MODULES);

?>

Notes

Note:
In versions of PHP before 5.5, parts of the information displayed are disabled when the expose_php configuration setting is set to off. This includes the PHP and Zend logos, and the credits.

Note:
phpinfo() outputs plain text instead of HTML when using the CLI mode.

A simple method to style your own phpinfo() output.

<style type="text/css">
#phpinfo {}
#phpinfo pre {}
#phpinfo a:link {}
#phpinfo a:hover {}
#phpinfo table {}
#phpinfo .center {}
#phpinfo .center table {}
#phpinfo .center th {}
#phpinfo td, th {}
#phpinfo h1 {}
#phpinfo h2 {}
#phpinfo .p {}
#phpinfo .e {}
#phpinfo .h {}
#phpinfo .v {}
#phpinfo .vr {}
#phpinfo img {}
#phpinfo hr {}
</style>

<div id="phpinfo">
<?php

ob_start () ;
phpinfo () ;
$pinfo = ob_get_contents () ;
ob_end_clean () ;

// the name attribute "module_Zend Optimizer" of an anker-tag is not xhtml valide, so replace it with "module_Zend_Optimizer"
echo ( str_replace ( "module_Zend Optimizer", "module_Zend_Optimizer", preg_replace ( '%^.*<body>(.*)</body>.*$%ms', '$1', $pinfo ) ) ) ;

This function parses the phpinfo output to get details about a PHP module. 


<?php

/** parse php modules from phpinfo */

function parsePHPModules() {

ob_start();

phpinfo(INFO_MODULES);

$s = ob_get_contents();

ob_end_clean();


$s = strip_tags($s,'<h2><th><td>');

$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);

$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);

$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);

$vModules = array();

 for ($i=1;$i<count($vTmp);$i++) {

  if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {

$vName = trim($vMat[1]);

$vTmp2 = explode("\n",$vTmp[$i+1]);

   foreach ($vTmp2 AS $vOne) {

$vPat = '<info>([^<]+)<\/info>';

$vPat3 = "/$vPat\s*$vPat\s*$vPat/";

$vPat2 = "/$vPat\s*$vPat/";

    if (preg_match($vPat3,$vOne,$vMat)) { // 3cols

$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3])); 

    } elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols

$vModules[$vName][trim($vMat[1])] = trim($vMat[2]); 

    } 

   } 

  } 

 } 

 return $vModules;

}

?>



Sample Output:

[gd] => Array

(

  [GD Support] => enabled

  [GD Version] => bundled (2.0.28 compatible)

  [FreeType Support] => enabled

  [FreeType Linkage] => with freetype

  [FreeType Version] => 2.1.9

  [Timezone Database] => internal

  [Default timezone] => America/Los_Angeles

  [Directive] => Array (

     [1] => Master Value

  )

  [date.timezone] => Array (

     [0] => no value

     [1] => no value

  )

 )



<?php

/** get a module setting */

function getModuleSetting($pModuleName,$pSetting) {

$vModules = parsePHPModules();

 return $vModules[$pModuleName][$pSetting];

}

?>



Example: getModuleSetting('gd','GD Version'); returns "bundled (2.0.28 compatible)"

<?php

// NOTE: When accessing a element from the above phpinfo_array(), you can do:
$array = phpinfo_array();

// This will work
echo $array["General"]["System "];  

// This should work also, but it doesn't because there is a space after System in the array.
echo $array["General"]["System"];  

// I hope the coder will fix it, so as to save someone else from wasting time. Otherwise, nice script.

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:

<?php

/* parse php modules from phpinfo */

function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();

$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
 for ($i=1;$i<count($vTmp);$i++) {
  if (preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
   foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
   if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
   } elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
   }
   }
  }
 }
 return $vModules;
}
?>

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).

<?php

ob_start ();

ob_start ();                              // Capturing
phpinfo ();                               // phpinfo ()
$info = trim (ob_get_clean ());           // output

// Replace white space in ID and NAME attributes... if exists
$info = preg_replace ('/(id|name)(=["\'][^ "\']+) ([^ "\']*["\'])/i', '$1$2_$3', $info);

$imp = new DOMImplementation ();
$dtd = $imp->createDocumentType (
'html',
'-//W3C//DTD XHTML 1.0 Transitional//EN',
'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'
);
$doc = $imp->createDocument (
'http://www.w3.org/1999/xhtml',
'html',
$dtd
);
$doc->encoding = 'utf-8';

$info_doc = new DOMDocument ('1.0', 'utf-8');
/* Parse phpinfo's output
 * operator @ used to avoid messages about undefined entities
 * or use loadHTML instead
 */
@$info_doc->loadXML ($info);

$doc->documentElement->appendChild ( // Adding HEAD element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('head')->item (0),
true                         // With all the subtree
)
);
$doc->documentElement->appendChild ( // Adding BODY element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('body')->item (0),
true                         // With all the subtree
)
);

// Now you get a clean output and you are able to validate...
/*
echo ($doc->saveXML ());
//      OR
echo ($doc->saveHTML ());
 */

// By that way it's easy to add some style declaration :
$style = $doc->getElementsByTagName ('style')->item (0);
$style->appendChild (
$doc->createTextNode (
'/* SOME NEW CSS RULES TO ADD TO THE FUNCTION OUTPUT */'
)
);

// to add some more informations to display :
$body = $doc->getElementsByTagName ('body')->item (0);
$element = $doc->createElement ('p');
$element->appendChild (
$doc->createTextNode (
'SOME NEW CONTENT TO DISPLAY'
)
);
$body->appendChild ($element);

// to add a new header :
$head = $doc->getElementsByTagName ('head')->item (0);
$meta = $doc->createElement ('meta');
$meta->setAttribute ('name', 'author');
$meta->setAttribute ('content', 'arimbourg at ariworld dot eu');
$head->appendChild ($meta);

// As you wish, take the rest of the output and add it for debugging
$out = ob_get_clean ();

$pre = $doc->createElement ('div'); // or pre
$pre->setAttribute ('style', 'white-space: pre;'); // for a div element, useless with pre
$pre->appendChild ($doc->createTextNode ($out));
$body->appendChild ($pre);

$doc->formatOutput = true; // For a nice indentation
$doc->saveXML ();

?>

All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

To extract all of the data from phpinfo into a nested array:
<?php
ob_start();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
    foreach($matches as $match)
        if(strlen($match[1]))
$phpinfo[$match[1]] = array();
        elseif(isset($match[3]))
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        else
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>

Some examples of using individual values from the array:

<?php
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
    echo "Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
    echo "License: {$phpinfo['PHP License'][0]}<br />\n";
?>

To display everything:

<?php
foreach($phpinfo as $name => $section) {
        echo "<h3>$name</h3>\n<table>\n";
        foreach($section as $key => $val) {
            if(is_array($val))
                echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
            elseif(is_string($key))
                echo "<tr><td>$key</td><td>$val</td></tr>\n";
            else
                echo "<tr><td>$val</td></tr>\n";
        }
        echo "</table>\n";
    }
?>

Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!

some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)

we need to change two lines:

<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>

and

<?php
preg_split( '/\n/', $matches[1] )
?>
to
<?php
preg_split( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>

That's all! Now we have a really flexible addition to phpinfo();

Simple JS snippet to print phpinfo() inline with it's styles renamed. Thus leaving the container page unaffected and pretty.

<script>
document.write(`<div id="phpinfo"><?php phpinfo(61) ?></div>`);
var x = document.querySelector('#phpinfo > style');
x.innerText = x.innerText.replaceAll('\n', '#phpinfo ');

Hi.

Here my version of saving php_info into an array:

<?php
function phpinfo_array()
{
ob_start();
phpinfo();
$info_arr = array();
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
$cat = "General";
    foreach($info_lines as $line)
    {
// new cat?
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
        if(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
$info_arr[$cat][$val[1]] = $val[2];
        }
        elseif(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
        {
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
        }
    }
    return $info_arr;
}

// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:

<?php
// start output buffering
ob_start();

// send phpinfo content
phpinfo();

// get phpinfo content
$html = ob_get_contents();

// flush the output buffer
ob_end_clean();

// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], '<i>no value</i>', $html);

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.


I have changed the preg_match_all() here so that the last <td></td> is optional


<?php

function parsePHPConfig() {

ob_start();

phpinfo(-1);

$s = ob_get_contents();

ob_end_clean();

$a = $mtc = array();

    if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))

        foreach($mtc as $v){

            if($v[2] == '<i>no value</i>') continue;

$a[$v[1]] = $v[2];

        }

    }

    return $a;

After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. &#039; into '), so I created my own by improving on the existing ones:

function phpinfo2array() {
    $entitiesToUtf8 = function($input) {
        // http://php.net/manual/en/function.html-entity-decode.php#104617
        return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
    };
    $plainText = function($input) use ($entitiesToUtf8) {
        return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
    };
    $titlePlainText = function($input) use ($plainText) {
        return '# '.$plainText($input);
    };

    ob_start();
    phpinfo(-1);

    $phpinfo = array('phpinfo' => array());

    // Strip everything after the <h1>Configuration</h1> tag (other h1's)
    if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
        return array();
    }

    $input = $matches[1];
    $matches = array();

    if(preg_match_all(
        '#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
        '(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
        $input, 
        $matches, 
        PREG_SET_ORDER
    )) {
        foreach ($matches as $match) {
            $fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
            if (strlen($match[1])) {
                $phpinfo[$match[1]] = array();
            } elseif (isset($match[3])) {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
            } else {
                $keys1 = array_keys($phpinfo);
                $phpinfo[end($keys1)][] = $fn($match[2]);
            }

        }
    }

    return $phpinfo;
}

The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):

Building on SimonD's elegant example to hide the logged-in username and password, which otherwise appear in plain text, the following should work for PHP 5.4+:

<?php
// start output buffering
ob_start();

// send phpinfo content
phpinfo();

// get phpinfo content
$html = ob_get_contents();

// flush the output buffer
ob_end_clean();

// remove auth data
if ( isset( $_SERVER[ 'PHP_AUTH_USER' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_USER' ], '[ protected ]' , $html);
    if ( isset( $_SERVER[ 'PHP_AUTH_PW' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_PW' ], '[ protected ]' , $html);

    echo $html;
?>

To remove additional items, just add them as above.

One note on the very useful example by "jon at sitewizard dot ca".  
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];

These two lines will produce the error "Strict Standards:  Only variables should be passed by reference in...".  The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:

Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];

Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];

This fixes the error. 
To wrap it all in an example:
<?php
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());

    if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER)){
        foreach($matches as $match){
        if(strlen($match[1])){
$phpinfo[$match[1]] = array();
        }elseif(isset($match[3])){
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
        }else{
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $match[2];      

        }

        }
}

    if(! empty($phpinfo)){
        foreach($phpinfo as $name => $section) {
            echo "<h3>$name</h3>\n<table class='wp-list-table widefat fixed pages'>\n";
            foreach($section as $key => $val){
                    if(is_array($val)){
                    echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
                    }elseif(is_string($key)){
                    echo "<tr><td>$key</td><td>$val</td></tr>\n";
                    }else{
                    echo "<tr><td>$val</td></tr>\n";
                }
            }
        }
            echo "</table>\n";
        }else{
    echo "<h3>Sorry, the phpinfo() function is not accessable. Perhaps, it is disabled<a href='http://php.net/manual/en/function.phpinfo.php'>See the documentation.</a></h3>";
    }
}
?>
Frankly, I went thought the trouble of adding this note because the example by "jon at sitewizard dot ca"  is probably the best on the web, and thought it unfortunate that it throws errors. Hope this is useful to someone.

Embedding phpinfo within your page, that already has style information:

The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.

Yes, we cheat on preparing the selector list.

<?php
ob_start();
phpinfo();

preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);

# $matches [1]; # Style information
# $matches [2]; # Body information

echo "<div class='phpinfodisplay'><style type='text/css'>\n",
join( "\n",
array_map(
create_function(
'$i',
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
),
preg_split( '/\n/', $matches[1] )
            )
        ),
"</style>\n",
$matches[2],
"\n</div>\n";
?>

Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:

-1, coded in 7 digits:
111 1111

look at this:
1+2+4+8+16+32+64=127

unsigned,127 is:
111 1111

so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1

so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2

so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>

hope this will be useful, that's my 1rst post ^^

I wanted a simple *function* to convert the output of phpinfo into an array.  Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c

Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.

== Sample Output ==
[PHP Configuration] => Array
 (
  [PHP Version] => 5.2.6
  [PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42
  [System] => Linux askapache 2.6.22.19-grsec3
  [Build Date] => Nov 11 2008 13:09:07
  [Configure Command] =>  ./configure --prefix=/home/grsec/bin/php 
  [Server API] => FastCGI

  [IPv6 Support] => enabled
 [Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42
  [PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
 )

[mbstring] => Array
 (
  [mbstring.http_input] => pass
  [mbstring.internal_encoding] => Array
    (
     [0] => ISO-8859-1
     [1] => no value
    )

  [mbstring.language] => neutral
   )

[mcrypt] => Array
 (
  [Version] => 3.5.7
  [Api No] => 20031217
 )

<?php
function phpinfo_array($return=false){
/* Andale!  Andale!  Yee-Hah! */
ob_start(); 
phpinfo(-1);

$pi = preg_replace(
 array('#^.*<body>(.*)</body>.*$#ms', '#<h2>PHP License</h2>.*$#ms',
'#<h1>Configuration</h1>#',  "#\r?\n#", "#</(h1|h2|h3|tr)>#", '# +<#',
"#[ \t]+#", '#&nbsp;#', '#  +#', '# class=".*?"#', '%&#039;%',
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)" alt="PHP Logo" /></a>'
.'<h1>PHP Version (.*?)</h1>(?:\n+?)</td></tr>#',
'#<h1><a href="(?:.*?)\?=(.*?)">PHP Credits</a></h1>#',
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)"(?:.*?)Zend Engine (.*?),(?:.*?)</tr>#',
"# +#", '#<tr>#', '#</tr>#'),
 array('$1', '', '', '', '</$1>' . "\n", '<', ' ', ' ', ' ', '', ' ',
'<h2>PHP Configuration</h2>'."\n".'<tr><td>PHP Version</td><td>$2</td></tr>'.
"\n".'<tr><td>PHP Egg</td><td>$1</td></tr>',
'<tr><td>PHP Credits Egg</td><td>$1</td></tr>',
'<tr><td>Zend Engine</td><td>$2</td></tr>' . "\n" .
'<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),
ob_get_clean());

$sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));
 unset($sections[0]);

$pi = array();
 foreach($sections as $section){
$n = substr($section, 0, strpos($section, '</h2>'));
preg_match_all(
'#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',
$section, $askapache, PREG_SET_ORDER);
   foreach($askapache as $m)
$pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
 }

 return ($return === false) ? print_r($pi) : $pi;
}

?>
