A Note About Publisher PHP Versions
PHP below 5.6 are out dated (PHP 5.6 support ended by the beginning of 2017). Publisher supports PHP 5.2.6 up to the latest version e.g. PHP 7, but it’s recommended, mostly due to security vulnerabilities, to use PHP 7.0 or higher.
Publisher supports PHP 7 and it’s recommended to use latest PHP version.
