note 70366 deleted from function.key by bobby

Note Submitter: jeroen schellekens Reason: in docs ---- <?php $arr = array( 0 => "katie", "0" => "john", "0 " => "suzy" ); foreach($arr as $k => $v) { print "[{$k}] => $v : Key " . (is_string($k) ? "is " : "is not") . " a string<br>"; } ?> outputs: [0] => john : Key is not a string [0 ] => suzy : Key is a string which means PHP treats "0" the same as 0 (both being a numeric entry in the array) and in this case declares entry 0 twice (initally as katie, then overwrites the same entry with john). I don't know whether this is a bug or not, but PHP automatically converts strings containing integers to integers, which in effect delivers a numeric entry in the array instead of an associative, which can be annoying in some situations. when you prepend / append any non-numeric character to the key (in my example "suzy"), it remains an associative entry in the array though.
