I don't like php
Why would anyone make a language with thousands of core functions that aren't organized into classes? It's near impossible to learn! It took me a month before I could remember the mysql_real_escape_string function! Maybe this is just me, but I find that it will act strange for no reason at all, and you'll spend hours upon hours trying to figure out what is wrong with your code. Sometimes I miss python, but I can't because most servers don't have python installed, and python is a bit trickier to setup since you need to set a content handler in either .htaccess or httpd.conf. But python is much nicer to work with, variables have methods like in JS, and I think it's much more organized. PHP seems to be a giant pool of functions. At least they have decent documentation for it though.
