Thanks, that was interesting :) I think I got one step further in understanding PHP :) BTW, I've changed the loop to 'for' and it's working well :) -----Original Message----- From: Robert Cummings [mailto:robert@xxxxxxxxxxxxx] Sent: Tuesday, July 05, 2011 4:45 PM To: Dajka Tamás Cc: php-general@xxxxxxxxxxxxx Subject: Re: Foreach question On 11-07-05 10:39 AM, Dajka Tamás wrote: > Ok, but if it would be that way I shouldn't get '122334455' for second output, no?

( since the first elements copy is pushed as third element, etc ) BTW, there are reasons you might calculate next item before iterating. If the current iteration removes the current item, then nextItem would still be valid (theoretically :). It's more often the case you might remove the current item, than try to remove the next item in a foreach iteration.
