67 well...to be honest, a lot of the problems I had that I wrote about where things I just never had to face before when working with PHP.
The not being able to read out of scope things? In JS I have that a lot of times, in Lua it also happens, in PHP though, this was the first time I had to do it (and even here I could have easily fixed worked around it).
The using a variable to get a certain thing out of an object? Again, first time in PHP but I use stuff like that plenty of times in Lua or JS.
Now, I am not saying PHP is good as it is not. The names in use for its functions are just bad. I mean eval() to execute a string? Or mt_rand()?
