What is PHP Selector and what is it used for?

PHP Selector enables your users to select a specific PHP version that they require for their hosting account. PHP Selector provides premium flexibility by offering the users all the popular versions of PHP, which enables them to keep old scripts without the obligation to use newer PHP versions or change the code of their website. The administrator manages PHP versions available to the users, as well as all available PHP extensions, and each user selects a PHP version using the interface and activates/deactivates extensions as necessary.
