phpinfo - Outputs information about PHP's configuration

SYNOPSIS
bool phpinfo ([int $what = INFO_ALL]) DESCRIPTION
Outputs a large amount of information about the current state of PHP. This includes information about PHP compilation options and exten- sions, 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(3) is commonly used to check configuration settings and for available predefined vari- ables on a given system. phpinfo(3) is also a valuable debugging tool as it contains all EGPCS (Environment, GET, POST, Cookie, Server) data. PARAMETERS
o $what - The output may be customized by passing one or more of the following constants bitwise values summed together in the optional $what parameter. One can also combine the respective constants or bitwise values together with the or operator. phpinfo(3) 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.

+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.5.0 | | | | | | | Logo GUIDs were replaced with data URIs, and so | | | turning off expose_php now has no effect on the | | | result of phpinfo(). Credits are also now embed- | | | ded within the output itself instead of linked. | | | | | 5.2.2 | | | | | | | The "Loaded Configuration File" information was | | | added, when before only "Configuration File | | | (php.ini) Path" existed. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 phpinfo(3) 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(3) outputs plain text instead of HTML when using the CLI mode. SEE ALSO
