Does anyone have any idea to this problem? All the code is in the emails I have written to the list. I have temporarily solved the problem by writing my own function not using any pregs, eregs, or any other regs and it works perfectly. It's probably not considered good programming, but it works the way it is supposed to. I would however like to know what the issue is with the original code, or if this is actually a bug in PHP.
