Agreed that PHP isn't terrible. Typically, it's the programmer's fault before it's the language's. Also, I agree that PHP isn't the right solution for every problem, but if you're set on using PHP for the wrong problems and need to bitch about it, see the previous sentence.
It's not that PHP is terrible. You can definitely write code in it that gets shit done.
It's that it exists in the same universe with Python, Ruby, Java, Clojure, Erlang, etc.
If you have the freedom to choose your implementation language, and those are your alternatives (to name just a few), that's when PHP is harder to justify. Not that it's terrible in isolation. In relative terms.
