note 12055 added to function.array.php

Notice that you can also add arrays to other arrays with the $array[] "operator" while the dimension doesn't matter. Here's an example: $x[w][x] = $y[y][z]; this will give you a 4dimensional assosiative array. $x[][] = $y[][]; this will give you a 4dimensional non assosiative array. So let me come to the point. This get interessting for shortening things up. For instance: foreach ($lines as $line){ if(!trim($line)) continue; $tds[] = explode("$delimiter",$line); } http://www.php.net/manual/en/function.array.php
