To be fair I was going to explain why it was a bad idea but I find reasoning with PHP developers very hard. As a recovering PHP developer myself, it will just be ignored.
You'll find that with more than just PHP :( I'm seeing it with Ruby and JS / Node too. Some developers are reasonable and great people but there's a subsection that think {Ruby, Python, PHP, JS} are the bees knees. I use all of those languages...
