• PHP Cache
  PHP has several cache extensions that can help speed up execution under certain circumstances. This is disabled by default. Enabling a cache extension does not necessarily improve performance. A particular cache will not be available for the current version of PHP if it is not enabled.

  Some caches provide a user interface to help analyze and profile your code. See the Tools menu on the WebStart section for links to these interfaces.

  • off
    Select this option if you do not want to use the PHP cache module.

  • APCu
    The APC User Cache is a free and open opcode cache for PHP. You can learn more about APCu here.

  • OPcache
    OPcache improves PHP performance by storing precompiled script bytecode in shared memory, eliminating the need for PHP to load and parse scripts on every request. You can learn more about OPcache here.

• My favorite link:
  A link to this address (URL or directory) will appear in the top menu of your WebStart page.

  If you enter “/subDirectory” in this field, the URL “http://localhost:8888/subDirectory” will be used.
