From the documentation :

"continue accepts an optional numeric argument which tells it how many levels of enclosing loops it should skip to the end of."

and we see that :

  var_dump(print "$r\n"); // int(1)

you see your problem here ? Anyway, the documentation should have a warning to avoid confusion.

This have been fixed in CVS.

I have added an example of what we shouldn't do when using continue, guess who wrote it ? ;)
