The phpinfo Function
The phpinfo function displays extensive information about the current PHP configuration,
including module information, PHP version, environment and server settings. The function accepts
an optional parameter that allows outputting only specific sections of information.
Syntax
phpinfo(int $flags = INFO_ALL);
Example
Let's output the complete PHP information:
<?php
phpinfo();
?>
The result will be an HTML page with detailed information about the PHP configuration.
Example
Let's output only the general PHP information:
<?php
phpinfo(INFO_GENERAL);
?>
The result contains only general information about the PHP version, system, and build.
Example
Let's get only the information about loaded modules:
<?php
phpinfo(INFO_MODULES);
?>
The result shows a list of all loaded PHP modules and their settings.
