Details of this construct were known for quite a long time, and it was available in PHP6 for "ages" it is a limited goto, just as advertised. you can get out of blocks with it, but you can't go into blocks -- Alexey Zakhlestin http://blog.milkfarmsoft.com/ --- ## #36798 — Daniel T.

I have yet to see a good case for goto (not break) that doesn't involve parsing or error handling, and we have exceptions already for error handling flow control. But, we don't have try ... finally (and java doesn't have goto). Best Regards, Jeff
