NAJAX is a PHP Ajax framework. Not only does it look easy to use, it also appears to have well-written and well-documented code.

One of the examples is a PHP Exam. I managed to score only 7 out of 12. A list of my errors in in the extended section of this article.

The errors

1. I confused array_shift with that of array_unshift. I always mix these two up.
2. I never heard of pcntl_exec before, so I didn't know why it was different than exec.
3. I didn't know how the === operator worked. I feel ashamed :) (it checks if both operands are the same and are of the same type)
4. I didn't know what the purpose of either get_required_files or get_included_files was. I guessed that they would be different, but in fact they are exactly the same. It returns an array with the names of included or required files.
5. I was fooled by the behavior of the ksort function: it does not return an array but rather applies the changes directly in the array passed to it, and returns a bool instead.

Hurray! I learned something today.
