My guess is that $newkey isn't an integer and therefore it is behaving differently than you expect it to behave. Might be a misfeature but then again it might not. Once we know what the type is we can think if what's happening makes sense or not. Andi It returns: string(20) "1 " (19 spaces in page source) Now I see why this happened. I should set $newkey to integer before incrementing it but, it shouldn't be that $var = $var + sth behaves diffrient that $var++. I think it should be changed that all variants behaves the same way.

Is that "1 " with a space after the 1? Don't forget that incrementing a string has a special meaning in PHP and therefore it behaves differently than adding it with an integer. If there weren't a space after the 1 then it should increment the string to "2". Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
