PHP is a popular web scripting programming language. MAMP PRO installs several versions of the PHP script interpreter.

MAMP


  • Default version
    Select which PHP version will be the default version. To view the php template file press the “+” button.

    Note: To remove unneeded PHP versions simply stop your servers, quit MAMP PRO, and remove your C:\MAMP\bin\php\phpX.XX directory, where X.XX is the version of PHP you want removed.

  • Make this version available on the command line
    Check this option to add the current PHP version to the system path. You verify this by checking your System PATH in Advanced System Settings > Environment Variables > System Variables.

  • Mode
    Choose whether to use identical PHP versions for all hosts (module mode) or on a host by host basis (CGI mode).

    • Identical PHP versions for all hosts (module mode)
      In module mode all hosts use the same PHP version.
    • Individual PHP version for every host (CGI mode)
      In CGI Mode the PHP settings will be identical for all hosts – except for the PHP version. Navigate to the Hosts section to change the PHP version for each individual host. More information on how to change the PHP version for an individual host is covered in the Settings > Hosts > General section.

  • Cache module to speed up PHP execution
    PHP has several cache extensions that can help speed up execution in certain circumstances. This is set to “off” by default. Enabling a cache extension does not necessarily translate into greater execution speed. A particular cache is not available for the current PHP version if it is not enabled.

    • off
      No cache will be used.
    • APC
      The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. You can learn more about APC here.
    • eAccelerator
      eAccelerator a free open-source PHP accelerator & optimizer. You can learn more about eaccelerator here.
    • XCache
      XCache is a open-source opcode cacher. You can learn more about xCache here.
    • OPCache
      OPcache improves PHP performance by storing precompiled script bytecode in shared memory, thereby removing the need for PHP to load and parse scripts on each request. You can learn more about OPcache here.

  • Extensions

    • Xdebug (Debugger)
      Activate Xdebug to allow PHP to create debugging information during script execution. By default, Xdebug uses localhost and port 9000 in the PHP.ini file.

    • Imagick / ImageMagick
      Activate Imagick / ImageMagick.

    • Tidy
      Activate Tidy.

    • Oauth
      Activate Oauth.

    • Open XDClient
      With Xdebug activated you can open the XDClinet debugger to enable PHP debugging. By default, XDClient expects debugging information on port 9000 of localhost.


  • What to log
    Determine which error types should be reported.

    • Display startup errors
      Log PHP errors that occur when Apache loads the PHP module.

    • All errors and warnings
      All errors will be reported.

    • Errors
      Script errors that make the further execution of the current PHP script impossible.

    • Warnings
      General errors in the PHP environment.

    • Notices
      Possible problems, that do not concern PHP, but which could be a notice of an error in a script.

    • Other
      Report further error types through constants. Please turn to the PHP documentation for further information.


  • Log Errors
    Determine if errors should be recorded in a log file and/or displayed in a web browser window.
