How to add a new version of PHP to the PHP toolbox

The website needs to use php-7.0 or above, but the ones in the [PHP Toolbox] are all with nts, and it seems to prompt a problem when shipping. Then I re-downloaded the latest version of PHP (downloaded from the http://www.php.net/ website). Now I need to use this new version in the [PHP Toolbox]. How? Add it and you can quickly switch and use it in this [PHP Toolbox].

My computer system is WIn7 Ultimate Edition
