I need to temporarily install PHP 5.5.9 in order to test an application upgrade. The installed version of the app is incompatible with PHP>5, and the current version is incompatible with PHP<7, so I need to upgrade to an intermediate version, upgrade PHP, and then do a final upgrade of the app...
I know PHP 5.5 is deprecated but I was wondering if there's still a way to install it somehow (preferably from ports)? I have a PHP script that only works with versions below PHP 5.6. Will it work if I install it from source?
