Enable a required PHP extension

Use PHP Selector to review modules without resetting working configuration.

Where Tools → Software → Select PHP Version → Extensions

Before you start

  • Get the exact extension name and required PHP version from your application’s documentation.
  • Record the current version and enabled extensions before changing them.

Steps

  1. 1

    Open Select PHP Version and read which PHP version and scope are active.

  2. 2

    Check the module only if the application needs it. Read any incompatibility or dependency message before continuing. Some selector changes take effect immediately.

  3. 3

    Do not click Reset PHP Extensions to default as a general troubleshooting step: it can remove a customised working set.

  4. 4

    Reload the application and confirm the feature works. If the extension remains unavailable, check the domain is using the selector-controlled runtime rather than a different MultiPHP configuration.

  5. 5

    Choose Extensions. Find the required module by its exact name, such as mysqli or redis; similar names are not always interchangeable.

    Extensions belong to the selected PHP runtime; the account scope matters.

Check it worked

  • The required extension is reported as loaded by the application or support.
  • Other websites sharing the same PHP configuration still work.
