This should be faster as it does not rely on preg for it's string parsing in all cases.
This is not directly compatible with the older versions due to the fact that I've changed around the order of the args for the entry function.
I really would like if you bring your work to the next level.
I am however writing it under PHP5, and it works good enough. Currently backing this thing with no issues thus far.
