RE: [PHP] unset($array[value]) does not work?

It is working. The last two tests you were running weren't actually the same, which was confusing your testing results. I've altered the code a little for ease of testing. It's included below. -----Original Message----- You will see that $unserialized['foo'] still exists! Can anyone explain me what I'm doing wrong? -------------------------- <? $array = array ( "foo" => "bar", "wom" => "bat" ); echo $array["foo"] . "<br>"; echo $array["wom"] . "<br>"; $serialized = serialize($array); echo $serialized . "<br>"; $unserialized = unserialize($serialized); echo $unserialized["foo"] . "<br>"; echo $unserialized["wom"] . "<br>"; echo "<hr>"; $keys = array_keys ($unserialized); echo $keys[0] . "<br>"; echo $keys[1] . "<br>"; echo "<hr>"; if (key_exists("foo", $unserialized)) { echo "foo exists!<br>"; } if (key_exists("wom", $unserialized)) { echo "wom exists!<br>"; } echo "<hr>"; unset ($unserialized['foo']); if (key_exists("foo", $unserialized)) { echo "foo exists!<br>"; } if (key_exists("wom", $unserialized)) { echo "wom exists!<br>"; } ?> **************************************************************************** This message is intended for the sole use of the individual and entity to whom it is addressed, and may contain information that is privileged, confidential and exempt from disclosure under applicable law.
