Extensions

The PHP Extensions page is accessed from Server Setup | Extensions.

The PHP Extensions page provides a convenient way to view and configure extensions.

Use this page to control and configure extensions that are loaded in your environment.
To find out how to add more extensions to this list, see Adding Extensions and UNIX: Compiling PHP Extensions for Zend Server.

PHP extensions are sets of instructions that add functionality to your PHP. Extensions can also be employed to recycle frequently used code. You can place a set of functions into one extension and instruct your projects to utilize the extension. Another use for PHP extensions is to improve efficiency and/or speed. Some processor intensive functions can be better coded as an extension, rather than as straight PHP code.

The Extensions page is list of the extensions included with the Zend Server for IBMi installation and extensions added to the php.ini by the user. Use the Extensions page to view the status of all your extensions and to quickly and easily load and unload extensions.

You can also configure directives associated with certain extensions. Extensions with directives that can be configured have a Configure link next to them.
Clicking the link opens the PHP Directives page, filtered to the exact directives associated with the particular extension. Click the All option in the PHP directives page to see a complete list of directives.

From this page, when applicable, for each extension you can:

Turn Off - The extension is not running on the machine and code that includes the Extension's functions works.
Turn On- The extension is running on the machine.
Built in- This applies to extensions that have dependencies, or were complied with PHP. Built-in extensions cannot be removed and thus do not have an On/Off option.
Directives - Clicking this link directs you to a pre-filtered view of the directives (in Server Setup | Directives) that belong to the extension.
View Description - at the end of each row of the table is a small icon that displays a tooltip that describes the component.
