Note Submitter: info at eastghost dot com ---- We noticed array_merge is relatively slower than manually extending an array: given: $arr_one[ 'x' => 1, 'y' => 2 ]; $arr_two[ 'a' => 10, 'b' => 20 ]; the statement: $arr_three = array_merge( $arr_one, $arr_two ); is routinely 200usec slower than: $arr_three = $arr_one; foreach( $arr_two as $k => $v ) { $arr_three[ $k ] = $v; } 200usec didn't matter...until we started combining huge arrays.
