I forgot, I have always used goto in Batch script, which indeed can emulates
functions, except there is no recursion problem. I have a couple of batches
online if interesting, and from performances point of view, ask yourself why on
earth PHP core developers have introduced goto and actually somebody is using
it ;-)
Uh, I forgot I live in microoptimization land ... lol
If you read the archives for PHP Internals you can view the discussion
that went into the final decision to include GOTO. It happened 2 or 3
years ago and I was certainly on the side arguing in its favour. The
GOTO used in languages such as C and now PHP, is not the bastard GOTO of
BASIC yesteryear. There are certainly use cases where the use of GOTO
makes far more sense than other constructs. Finite state machines (often
used in parsing) are one such place. In fact if you grep for goto on any
major open source project's C code, you will probably find multiple
occurrences. PHP, MySQL, and Apache all use goto.
