I was working for a company doing mostly COBOL programming about a year ago, and I can honestly say that GOTO can be used neatly and effectively, but it can also turn code into a horrible mess. For COBOL, it's an absolute must. There are no while or for loops in COBOL (at least not in the version we were using), so you had to replicate that with GOTO's and paragraphs. For PHP, I really don't see this as necessary.

So long as it's not widely publicized in tutorials and the like, I don't really see a whole lot of novice coders getting their hands on this. I'm not particularly concerned about experienced programmers using GOTO in PHP, especially if they've used in another language where it is more necessary.
