Processwire on Ubuntu Issue - Outputting code instead of Executing

[FrancisChung]

Hi there,
A colleague of mine is trying to get our site running on his local Ubuntu LAMP Setup (Ubuntu 17.10, Apache 2.4.27, PW 3.0.62, PHP 7.1.11)

When he types in the Homepage URL, he's getting code outputted instead of being executed.
Does any one know why?

Update : 

Just Figured it out.
Apparently, it's a new PHP7 security feature that disables from code executing if the code module starts with <? instead of <php
I'm using MAMP locally so I'm guessing MAMP is somehow circumventing this but LAMP isn't.

I'm posting this so people can save themselves hours pulling their hair out.

If I'm getting this right, you're talking about short open tags? That's not exactly a new thing, but rather something that users have been discouraged to use for a very long time. Though you can still enable short open tags with the short_open_tag php.ini setting, if you've still got code that relies on short opening tags, you should consider updating it to the regular <?php opening tags

That being said, in PHP7 they did remove some utterly obsolete tags: the ASP style tags (<% %>) and the script tags (<script language="php"></script>). My guess is that most users probably didn't even know that those existed.

Thanks for your advice. I will do as suggested. Never expected a simple syntax idiosyncrasy like that would completely catch me out.
