note 82302 added to language.operators.comparison

Hi all: I found this and maybe it can help you, i didn't found it documented anywhere : Assuming you have a function that returns an array or a null value in failure and you do something like this <?php function myfunction() { if($something==$other) { return array(0=>array(0=>array('valor'=>$other))); }else{ return null; } } $x = myfunction(); var_dump($x); //can be null if($x[0][0]['value'] < 1) { echo "nok"; }else{ echo "ok"; } ?> If the function returns null then you get "nok" printed. As far as I see NULL values are always less than 1, and the fact that I request a sub array ([0][0]['value']) doesn't give me any notice nor warning. Hope this helps anybody.
