Before i start to read the whole source please tell me if php act
according to the rules.
Once again - when i create the following array with apostrophes
<http://odge.de/englisch-deutsch/apostrophe.html> in php
arr['\0'] = ...
the output from <<print_r>> is as follow: Array( [\0] ...)
When i create the array with quotes the output is as follow:
arr["\0"] = ... Array ( Null Byte)
When i create the array from the url with register globals on
arr[%00] the output is as follow: Simply nothing !
PS: read the php source, 'array's are implemented in Zend/zend_hash.c
I know that i could do this, but it cost a lot of time and
therefor i decided
to ask someone who may had the same problem :-)
regards
Steve
