So can avoid all the changes from $test to $testArray (testef with E_ALL).

$test = explode('/',$test);
$mask = (isset($test[1])) ? $test[1] : '';
$test = $test[0];

But it's going to be a PITA if we try to avoid *notices*. If you notices 
such stuff how about all the unitinitalited-variables warnings which must 
be all over the place.
