Go figure, i’d like to have php-5 but all that’s there is php-7 so i find it easier to reboot into debian-jessie where i’ve already gone through the ridiculous ■■■■■■■■ required to configure PHP+ncurses and i don’t have to waste the time it would take me to build php from source and then screw with all the Zend proprietary garbage, and then go back and set up the goddam PHP ini file again because some clown has twiddled the default ini file again.
