    Phar::webPhar — Routes a request from a web browser to an internal file within the phar archive

    Description

    final public static Phar::webPhar(
        ?string $alias = null,
        ?string $index = null,
        ?string $fileNotFoundScript = null,
        array $mimeTypes = [],
        ?callable $rewrite = null
    ): void

    Phar::webPhar() serves as Phar::mapPhar() for web-based phars. This method parses $_SERVER['REQUEST_URI'] and routes a request from a web browser to an internal file within the phar archive. It simulates a web server, routing requests to the correct file, echoing the correct headers and parsing PHP files as needed. Combined with Phar::mungServer() and Phar::interceptFileFuncs(), any web application can be used unmodified from a phar archive.

    Phar::webPhar() should only be called from the stub of a phar archive (see here for more information on what a stub is).

    Parameters

    alias

    The alias that can be used in phar:// URLs to refer to this archive, rather than its full path.

    index

    The location within the phar of the directory index.

    fileNotFoundScript

    The location of the script to run when a file is not found. This script should output the proper HTTP 404 headers.

    mimeTypes

    An array mapping additional file extensions to MIME type. If the default mapping is sufficient, pass an empty array. By default, these extensions are mapped to these MIME types:

    <?php
    $mimes     = array(
    'phps' => Phar::PHPS, // pass to highlight_file()
    'c' => 'text/plain',
    'cc' => 'text/plain',
    'cpp' => 'text/plain',
    'c++' => 'text/plain',
    'dtd' => 'text/plain',
    'h' => 'text/plain',
    'log' => 'text/plain',
    'rng' => 'text/plain',
    'txt' => 'text/plain',
    'xsd' => 'text/plain',
    'php' => Phar::PHP, // parse as PHP
    'inc' => Phar::PHP, // parse as PHP
    'avi' => 'video/avi',
    'bmp' => 'image/bmp',
    'css' => 'text/css',
    'gif' => 'image/gif',
    'htm' => 'text/html',
    'html' => 'text/html',
    'htmls' => 'text/html',
    'ico' => 'image/x-ico',
    'jpe' => 'image/jpeg',
    'jpg' => 'image/jpeg',
    'jpeg' => 'image/jpeg',
    'js' => 'application/x-javascript',
    'midi' => 'audio/midi',
    'mid' => 'audio/midi',
    'mod' => 'audio/mod',
    'mov' => 'movie/quicktime',
    'mp3' => 'audio/mp3',
    'mpg' => 'video/mpeg',
    'mpeg' => 'video/mpeg',
    'pdf' => 'application/pdf',
    'png' => 'image/png',
    'swf' => 'application/shockwave-flash',
    'tif' => 'image/tiff',
    'tiff' => 'image/tiff',
    'wav' => 'audio/wav',
    'xbm' => 'image/xbm',
    'xml' => 'text/xml',
    );
    ?>
    rewrite

    The rewrites function is passed a string as its only parameter and must return a string or false.

    If you are using fast-cgi or cgi then the parameter passed to the function is the value of the $_SERVER['PATH_INFO'] variable. Otherwise, the parameter passed to the function is the value of the $_SERVER['REQUEST_URI'] variable.

    If a string is returned it is used as the internal file path. If false is returned then webPhar() will send a HTTP 403 Denied Code.

    Return Values

    No value is returned.

    Errors/Exceptions

    Throws PharException when unable to open the internal file to output, or if called from a non-stub. If an invalid array value is passed into mimeTypes or an invalid callback is passed into rewrite, then UnexpectedValueException is thrown.

    Changelog

    Version Description
    8.0.0 fileNotFoundScript and rewrite are nullable now.

    Examples

    Example #1 A Phar::webPhar() example

    With the example below, the created phar will display Hello World if one browses to /myphar.phar/index.php or to /myphar.phar, and will display the source of index.phps if one browses to /myphar.phar/index.phps.

    <?php
    // creating the phar archive:
    try {
    $phar = new Phar('myphar.phar');
    $phar['index.php'] = '<?php echo "Hello World"; ?>';
    $phar['index.phps'] = '<?php echo "Hello World"; ?>';
    $phar->setStub('<?php
    Phar::webPhar();
    __HALT_COMPILER(); ?>'    );
    } catch (    Exception $e) {
    // handle error here
    }
    ?>

    It seems that calling Phar::webPhar() from inside a function is a bad idea. Doing so will cause global variables in included files to not be global. For instance, do NOT try this:

    <?php
    $phar     = new Phar('test.phar.php');
    $phar['test.php'] = '<?php
    $FOO = "globals work";
    function test() {
    global $FOO;
    echo "test: $FOO\n";
    }
    test();
    ?>'    ;
    $phar->setStub('<?php
    function _bootstrap() {
    Phar::webPhar();
    }
    _bootstrap();
    __HALT_COMPILER(); ?>'    );
    ?>

    The output will be "test:", not "test: globals work".
