read the php source, 'array's are implemented in Zend/zend_hash.c :) On 11/10/06, Stefan Lochbihler <steve01 () chello at> wrote:
Hi guys, some questions to NULL Bytes within PHP Arrays. Let us assume there exist a php script with the following code. $erg=$_GET['show'] if(!isset($arr[$erg]) $erg="something"; $arr is a predefined variable but with "register globals on" it would be possible to set your own Array Key. This means when you set $erg=test $arr[test] you could deliver almost every chars you want. My problem is that i want to deliver a content like that. $erg=index.html%00 $arr[index.html%00] The problem is that the Null Byte within the array destroy the array. My question is if there exist a way to avoid the Null Byte within the array. For example (im not really familiar with charsets) to create the Null Byte with the help of f.e. UTF-7 encoded chars. If someone has an idea please let me know. Best regards Steve _______________________________________________ Full-Disclosure - We believe in it.
