Update, never mind. Just realized scl only affects the current shell. As soon as I logged out and back in, it reverted. Thanks
I used the command to set my bash to use PHP 7.2 doing this:
scl enable rh-php72 bash
Well I changed my mind. How do I go back to the the installed php 5.4x ? There doesn't seem to be a command for this.
Trying to search online for a solution but it's kind of vague.
