phpdockerio/php56-cli repository overview

⁠PHPDocker.io - PHP 5.6 / FPM container

Debian Jessie PHP 5.6 / CLI container for PHPDocker.io⁠ projects.

Smaller in size than PHP's official container (200MB vs 460MB) plus you don't need to install any build dependencies let alone compile anything, Debian Jessie already ships binaries for the vast majority, if not all, of PHP extensions.
