===== Apache & PHP: Required Modules =====
==== Required Modules ====

**[[http://www.php.net/manual/en/book.simplexml.php|SimpleXML]]** is used by GetSimpleCMS for efficient XML document manipulation.\\
The extension is enabled by default in most distros. To be sure //for local development//, open a terminal and list all PHP modules by typing:

  php -m
  
//For remote servers//, upload a file phpinfo.php with the following contents:

  <?php phpinfo(INFO_MODULES); ?>
  
..navigate to it in the browser, and search for SimpleXML.
If SimpleXML is not in the list, you need to [[http://www.php.net/manual/en/simplexml.installation.php|install it]].

==== Important but not Absolutely Required Modules====

  * [[http://www.php.net/manual/en/zip.installation.php|ZipArchive]] - For making zip [[how_to:backup_website|backups]] of your website. If you do not have this installed, GS will try to use the [[http://php.net/manual/en/book.zlib.php|zlib library]] to create .tar.gz files instead of .zip .
  * [[http://httpd.apache.org/docs/current/mod/mod_rewrite.html|Apache mod_rewrite]] - This is only needed if you want to use [[:pretty_urls|FancyURLs]] (set within the control panel's 'settings' page). aka **rewrite_module**.
  * [[http://www.php.net/manual/en/curl.setup.php|Curl]] - Curl is needed to connect to our API to check for GetSimple updates. 
  * [[http://www.php.net/manual/en/image.installation.php|GD Library]] - This module is needed in order to create thumbnails on uploaded images.
