PHP settings

You can choose which version of PHP to run in your .magento.app.yaml file:

name: mymagento
type: php:<version>

Configure PHP

You can customize the PHP settings for your environment using a php.ini file that is appended to the configuration maintained by Adobe Commerce.

In your repository, add the php.ini file to the root of the application (the repository root).

Increase PHP memory limit

To increase the PHP memory limit, add the following setting to the php.ini file:

memory_limit = 1G

For debugging, increase the value to 2G.

Optimize realpath_cache configuration

Set the following realpath_cache settings to improve application performance.

;
; Increase realpath cache size
;
realpath_cache_size = 10M

;
; Increase realpath cache ttl
;
realpath_cache_ttl = 7200

These settings allow PHP processes to cache paths to files instead of looking them up for each page load. See Performance Tuning in the PHP documentation.

Check custom PHP settings

After pushing the php.ini changes to your Cloud environment, you can check that the custom PHP configuration has been added to your environment. For example, use SSH to log in to the remote environment and view the file using something similar to the following:

cat /etc/php/<php-version>/fpm/php.ini

Enable extensions

You can enable or disable PHP extensions in the runtime:extension section. Also, the extensions specified become available in the Docker PHP containers.

Example in .magento.app.yaml file:

runtime:
    extensions:
        - sockets
        - sodium
        - ssh2
    disabled_extensions:
        - bcmath
        - bz2
        - calendar
        - exif

Use SSH to log in to an environment and list the PHP extensions.

php -m

For details about a specific PHP extension, see the PHP Extension List.

The following table shows the supported PHP extensions when deploying Adobe Commerce on the Cloud platform.

PHP module requirements are tied to the Adobe Commerce version. See PHP requirements.

Extension support

For Pro projects, the following extensions require additional support to install:

• sourceguardian

For example, to set up PHP to execute only SourceGuardian-protected scripts in all environments, the following option must be set in the php.ini file:

[SourceGuardian]
sourceguardian.restrict_unencoded = "1"

See section 3.5 of the SourceGuardian documentation. This is a link to a PDF.

Submit an Adobe Commerce Support ticket to install these PHP extensions in all Production environments and Pro Staging environments. Include your updated .magento/services.yaml file, .magento.app.yaml file with the updated PHP version and any additional PHP extensions. For changes to a live Production environment, you must provide a minimum of 48 hours notice. It can take up to 48 hours for the Cloud infrastructure team to update your project.
