PHP application | Magento 2 Developer Documentation

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

name: mymagento
type: php:<version>

PHP extensions

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

.magento.app.yaml

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

PHP compiled with debug is not supported and the Probe may conflict with XDebug or XHProf. Disable those extensions when enabling the Probe. The Probe conflicts with some PHP extensions like Pinba or IonCube.

Custom PHP configuration

You can customize the PHP settings for a Cloud environment by adding a php.ini file to your project. See Customize PHP.INI.
