[PHP-DEV] PHP 4.0 Bug #7621: NULL-bytes cause fundamental problems in string processing From: vburwitz <email protected>
Date: 11/03/00

From: vburwitz <email protected>
Operating system: GNU/Linux 2.2.13 (SuSE 6.3)
PHP version: 4.0.3pl1
PHP Bug Type: Scripting Engine problem
Bug description: NULL-bytes cause fundamental problems in string processing

Fundamental String Append Problem!!!

If NULL-bytes are in a string then appending the string won't work.

e.g. (NULL-byte written as "0" here)

$a ="abc0def";
$b ="1230456";

$a .=$b;

echo $a;
=> "abc"

echo strlen($a);
=> "3"

Well I don't have to mention that the problem is most probably
related to NULL-termination of strings in C/C++.

The above creates a lot of HUGE PROBLEMS and was working
with PHP3, since I am depending on NULL-safe string processing.

Could someone give me a fast reply if something more is known?

Thanks

V. Burwitz
