# Easy installation of PHP extensions in official PHP Docker images This repository contains a script that can be used to easily install a PHP extension inside the [official PHP Docker images](https://hub.docker.com/_/php/). ## Known limits Currently the script requires the Debian-based images (no Alpine). ## Usage Here's a sample Dockerfile that installs the GD and xdedub extensions inside a docker image: ``` FROM php:7.2-cli ADD https://raw.githubusercontent.com/mlocati/docker-php-extension-installer/master/install-php-extensions /usr/local/bin/ RUN install-php-extensions gd xdebug ``` ## Supported PHP extensions | Extension | PHP 5.6 | PHP 7.0 | PHP 7.1 | PHP 7.2 | |:---:|:---:|:---:|:---:|:---:| | apcu | | V | V | V | | bcmath | V | V | V | V | | bz2 | V | V | V | V | | calendar | V | V | V | V | | cmark | | V | V | V | | dba | V | V | V | V | | enchant | V | V | V | V | | exif | V | V | V | V | | gd | V | V | V | V | | gettext | V | V | V | V | | gmp | V | V | V | V | | imagick | V | V | V | V | | imap | V | V | V | V | | interbase | V | V | V | V | | intl | V | V | V | V | | ldap | V | V | V | V | | mcrypt | V | V | V | | | memcache | V | | | | | memcached | V | V | V | V | | mysql | V | | | | | mysqli | V | V | V | V | | odbc | V | V | V | V | | opcache | V | V | V | V | | pcntl | V | V | V | V | | pdo_dblib | V | V | V | V | | pdo_firebird | V | V | V | V | | pdo_mysql | V | V | V | V | | pdo_odbc | V | V | V | V | | pdo_pgsql | V | V | V | V | | pdo_sqlsrv | | V | V | V | | pgsql | V | V | V | V | | pspell | V | V | V | V | | pthreads | V | V | | | | recode | V | V | V | V | | redis | V | V | V | V | | shmop | V | V | V | V | | snmp | V | V | V | V | | soap | V | V | V | V | | sockets | V | V | V | V | | solr | V | V | V | | | sqlsrv | | V | V | V | | ssh2 | V | V | V | V | | sybase_ct | V | | | | | sysvmsg | V | V | V | V | | sysvsem | V | V | V | V | | sysvshm | V | V | V | V | | tidy | V | V | V | V | | timezonedb | V | V | V | V | | uuid | V | V | V | V | | wddx | V | V | V | V | | xdebug | V | V | V | V | | xmlrpc | V | V | V | V | | xsl | V | V | V | V | | yaml | V | V | V | V | | zip | V | V | V | V | ## Special requirements Some extension has special requirements: | Extension | Requirements | |:---:|:---:| | pthreads | Requires images with PHP compiled with thread-safety enabled (`zts`). |
