continue
continue - optional trailing block in a while or foreach 
continue BLOCK
Actually a flow control statement rather than a function.  If there is a
continue
 BLOCK attached to a BLOCK (typically in a while or
foreach), it is always executed just before the conditional is about to
be evaluated again, just like the third part of a for loop in C.  Thus
it can be used to increment a loop variable, even when the loop has been
continued via the 
next
 statement (which is similar to the C 
continue
statement).
