PHPinfo

The PHPinfo screen is a read-only screen that outputs a large amount of information about the current state of PHP. It is an easily accessible representation of information contained in the php.ini file, including information about PHP compilation options and extensions, the PHP version, server information and environment, PHP environment, OS version information, paths, master and local values of configuration options, HTTP headers and the PHP License.

Changing phpInfo

Zend Core's GUI allows easy changing of PHPinfo through the Configuration tab. Any changes made to the extensions and directives in this tab will be automatically updated in your php.ini file and will be reflected in the PHPinfo tab.

Note:

Configuration changes will only take effect once the server has been restarted.

More information about the PHPinfo display can be found in the PHP Manual, accessed by going to the Documentation Tab | PHP and clicking on "PHP Options and Information", Chapter VI., section LV.
