How to Install PDO Driver in PHP Docker Image

This article addresses the issue of installing the PDO driver for PHP within a Docker container. The provided PHP Docker image with the tag "php:5.6-apache" does not include the PDO driver by default.

Problem

The error message "Fatal error: Uncaught exception 'PDOException' with message could not find driver" indicates that the PDO driver is missing. Attempts to install the "php-mysql" component via "apt-get install php5-mysql" and add a "mysql.ini" file in "/usr/local/etc/php/conf.d/" were unsuccessful.

Solution

The docker-php-ext-install script, provided by the official PHP Docker repository, can be used to install the PDO driver.

FROM php:5.6-apache

# PHP extensions

RUN docker-php-ext-install pdo pdo_mysql

This command will install both the PDO and the PDO_MYSQL extensions within the Docker container.
