Comments:
user replied that problem is partly solved, anyway there's one NS4.x issue remaining
try this...
<?php
echo "abc\0XXX";
echo 'XXY'.str_repeat('as',60);
?>
NS4.x (mozilla,IE etc. won't) simply does not recognize a bunch of characters, it's
apparently a Netscape bug and I'm sure we can't do anything here to improve the situation
any ideas anyone?

PHP 3 problem?

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

hm, works for me (4.0.4dev win32)... strlen() is ok. output
is ok.

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
