laravel I think its php tokenizer

People at work got a hold of my computer and broke a bunch of stuff downgrading from php7 to 5.6(it worked before), I tried booting up my laravel project and I get this error

FatalErrorException in BladeCompiler.php line 160: Call to undefined function Illuminate\View\Compilers\token_get_all()

The few articles I've found seem to point to php tokenizer being the problem. Laravel Call to undefined function Illuminate\View\Compilers\token_get_all()

I reinstalled php 5.6 on my computer and I used –enable-tokenizer only to get command not found. I do recall my php.ini file not being replaced when I unistalled php so I wonder if that has something to do with it.

I'm on ubuntu 16.04 will anyone out there can help me figure this out?
