Default paths

• Default Docker working directory: /var/www/html
• Additional PHP .ini files to load: /usr/local/etc/php/conf.d
• Custom PHP .ini file generated (only if ENV_SUBSTITUTION_ENABLE=true): /usr/local/etc/php/conf.d/default-php.ini

Configurable Environment Variables

PHP-FPM and PHP configurations can be overwritten using environment variables. To do so, just indicate the substitution of values using ENV_SUBSTITUTION_ENABLE=true (since it is disabled by default).

Below are the environment variables with their default values:

PHP-FPM

Global FPM

Settings replaced into /usr/local/etc/php-fpm.conf file.

• PHP_FPM_ERROR_LOG=/proc/self/fd/2
• PHP_FPM_LOG_LEVEL=error

FPM WWW Pool

Settings replaced into /usr/local/etc/php-fpm.d/www.conf file.

• PHP_FPM_LISTEN=9000
• PHP_FPM_USER=www-data
• PHP_FPM_GROUP=www-data
• PHP_FPM_LISTEN_OWNER=www-data
• PHP_FPM_LISTEN_GROUP=www-data

PHP Config

Settings replaced into /usr/local/etc/php/conf.d/default-php.ini file (php.ini).

• PHP_MEMORY_LIMIT=512M
• PHP_EXPOSE_PHP=On
• PHP_SESSION_GC_MAXLIFETIME=1440

Disable PHP additional extensions

The PHP additional extensions can be disabled at startup by providing the PHP_DISABLE_EXTENSIONS environment variable with one or more names. For example PHP_DISABLE_EXTENSIONS=psr,exif,bz2.

Find the valid extension names in extensions.txt file of every PHP version directory or by using php -m. For example docker run --rm joseluisq/php-fpm:8.3 php -m | grep "exif".
