On the server where you encounter the problem, run this script and
paste the output here:
<?php
echo phpversion() . "\n";
foreach(array("\x00D" => 1) as $k => $v) {
echo bin2hex($k);
};
echo "done\n";
?>

The bug is in arrays. When you iterate through whole array some of the
keys (which has "\x00" as first character) returned by
foreach ($arr as $k => $v)
are incorrect. Empty string is returned in $k.

What exactly is the bug?
In the arrays or in the contents of the file?
How are you testing it?
(you need to be more specific if you want someone else to be able to
reproduce it)

Description:
------------
I use PHP on WinXP and Linux box. Older versions had bug with array
keys starting wuth "\x00" character. Now there is no such bug on my
computers (WinXP/Apache/php-4.3.4-Win32 & php-4.3.6-Win32 or
Linux/Apache 1.3.29/PHP 4.3.4), but some of the script's users complain
that script works on Windows box but does not on server. So, I guess
that some of the versions still have this bug (like
MacOSX/Apache/PHP4.3.2 or BSD/Apache/PHP4.3.4, as reported by users).
Reproduce code:
---------------
$key = "\x00\x00";
$arr[$key] = 1;
$key = "\x00\x44";
$arr[$key] = 2;
$key = "\x44\x44";
$arr[$key] = 3;
$fp = fopen("test","wb");
foreach ($arr as $k => $v) {
fwrite($fp,"'$k' => $v\n");
}
Expected result:
----------------
'\x00\x00' => 1
'\x00D' => 2
'DD' => 3
/* instead of "\x00" zero-character should be written to file */
Actual result:
--------------
'' => 1
'' => 2
'DD' => 3
