PHP configuration (php.ini)

Base php.ini file

By default, the base php.ini file is the development php.ini file that comes with PHP. The TEMPLATE_PHP_INI variable selects the production one instead:

TEMPLATE_PHP_INI=production

Setting php.ini parameters

The PHP_INI_<parameter> environment variables set any php.ini parameter:

services:
  my_app:
    image: thecodingmachine/php:8.4-v5-apache
    environment:
      # memory_limit=1g
      PHP_INI_MEMORY_LIMIT: 1g
      # error_reporting=E_ALL
      PHP_INI_ERROR_REPORTING: E_ALL

If the parameter contains a dot (.), replace it with a double underscore (__):

# opcache.validate_timestamps=0
PHP_INI_OPCACHE__VALIDATE_TIMESTAMPS=0
# intl.default_locale=fr_FR.UTF-8
PHP_INI_INTL__DEFAULT_LOCALE=fr_FR.UTF-8

The parameters are applied to PHP CLI and to the PHP of the apache or fpm variant.
