PHP 4.0 Bug #7621 Updated: NULL-bytes cause fundamental problems in string processing

ID: 7621 Updated by: waldschrott Reported By: vburwitz@mails-media.de Status: Feedback Bug Type: Scripting Engine problem Assigned To: Comments: your example (duped out) with chr(0) again works for me, I tested now on win32 (4.0.4dev) AND linux(4.0.3dev), both are ok. perhaps anyone else can try to verify Previous Comments: --------------------------------------------------------------------------- [2000-11-03 13:31:25] waldschrott@php.net hm, works for me (4.0.4dev win32)... strlen() is ok. output is ok. --------------------------------------------------------------------------- [2000-11-03 09:28:45] vburwitz@mails-media.de 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.
