Does glitch support PHP?

Does glitch support/have PHP installed? If so what version?

I think they generally advise that you remix an existing project running PHP – this might point you in the right direction

Hey @SpeedyCraftah Glitch project containers currently have PHP 7 installed:

app@anonymous-anaconda:~ 13:13 
$ php -v
PHP 7.0.33-0ubuntu0.16.04.5 (cli) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache v7.0.33-0ubuntu0.16.04.5, Copyright (c) 1999-2017, by Zend Technologies

The post @househaunt linked to gives some additional guidance on using PHP on Glitch.
