PHP 4.0 Bug #5688: Unset() inconsistent treatment of resource values not as integers

From: mlemos@acm.org Operating system: Linux RH 6 PHP version: 4.0.0 PHP Bug Type: Misbehaving function Bug description: Unset() inconsistent treatment of resource values not as integers Resource values like those returned by ImageCreate() are integers, despite when they are echo'ed they expand to something like "Resource id #nnn". However, it seems that when a resource value is used and array index, Unset() does not take it as an integer unless you explicitly cast the value. Try this script to see the problem. <? $resource=ImageCreate(1,1); $array=array(); $array[$resource]=1; Unset($array[$resource]); echo IsSet($array[$resource])," ",serialize($array)," ",$resource," ",intval($resource),"\n"; Unset($array[intval($resource)]); echo IsSet($array[$resource])," ",serialize($array)," ",$resource," ",intval($resource),"\n"; ?>
