Re: ++$i++ (was Re: [PHP-DEV] call_builtin_function_array() possible?)

I recently needed to process every other element of a numerically indexed array. for( $i = 0 ; $i < count( $a ) ; $x = $a[ ++$i++ ] ) would have saved me one statement. I had to use for( $i = 0 ; $i < count( $a ) ; $x = $a[ $i++ ] , $i++ ) I know, this is an 'issue' so tiny I can laugh at it, but anyway...
