PHP Extensions<\/h2>\n

PHP application servers on the platform have many built-in modules. This enables you to configure distinct PHP extensions for the PHP-FPM (NGINX-PHP) and httpd (Apache-PHP) daemons. Several frequently used extensions come pre-installed and are by default operated by PHP:<\/p>\n

ctype<\/td>\nhash<\/td>\n<\/td>\n<\/tr>\n

filter<\/td>\nReflection<\/td>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
<\/div>\n

The Remaining extensions are dynamic, which means that they are part of the server builds (kept in a separate modules folder) and can be enabled when required:<\/p>\n

Below, You Can Learn How To<\/h2>\n
    \n
  1. Activate an extension<\/a><\/li>\n
  2. Configure an extension<\/a><\/li>\n
  3. Add your custom extension<\/a><\/li>\n<\/ol>\n

    1. Activate Extension<\/h3>\n

    To make a dynamic extension available for the PHP module (i.e., engine) you’re using, it needs to be enabled in the corresponding configuration file.<\/p>\n

    Here\u2019s how you can enable a dynamic extension for the PHP module:<\/p>\n

    Step 1.<\/strong> Click the “Config”<\/a> button for your app server.<\/p>\n

    \"Config\"<\/a><\/p>\n

    Step 2.<\/strong> Locate the `etc > php.ini` file in the configuration tab that is opened, then scroll down to the “Extensions provided by PaaS” section. This section contains a subsection for each dynamic extension where you can enable and configure it.<\/p>\n

    \"php.ini<\/a><\/p>\n

    Step 3.<\/strong> Now, find the necessary section (they are arranged alphabetically) and remove the {extension={module_name} comment. To enable the so{ directive, remove the semicolons at the beginning of the appropriate line:<\/p>\n

    \"Edit<\/a><\/p>\n

    You can also modify the extension by adding your configuration parameters or by using the ones that are already supplied.<\/p>\n

    Step 4.<\/strong> After making all the necessary changes, remember to save them and restart the node to apply the new configuration.<\/p>\n

    \"Restart<\/a><\/p>\n

    2. Configure Extension<\/h3>\n

    The `php.ini` file manages all of the required PHP module settings. The majority of the offered dynamic extensions have a list of potential setup options.<\/p>\n

    As an example, here are some settings for the dynamic OPcache extension, a PHP accelerator based on opcode caching and optimization:<\/p>\n
