php-config is a simple shell script for obtaining information about the installed PHP configuration.
When the extensions are being compiled, if multiple PHP versions are installed, the installation for which to build can be specified by using the --with-php-config option during configuration, setting the path of the respective php-config script.
The list of command line options provided by the php-config script can be queried anytime by running php-config with the -h switch:
Usage: /usr/local/bin/php-config [OPTION] Options: --prefix [...] --includes [...] --ldflags [...] --libs [...] --extension-dir [...] --include-dir [...] --php-binary [...] --php-sapis [...] --configure-options [...] --version [...] --vernum [...]
