ok, problem here is that php_stripslashes for sybase_magic_quetes
replace '\0' with ascii(0) due reverse action on php_addslashes.

IMHO in contrary to ''' type replacements where we "maintains" the
data "queues fixed" all over the script, on ascii(0) data, we have no
problem do it onto the query level.
there'll be minore bc problem but the current beavior is totally bogus!

well, using set_magic_quotes_runtime(0); fix the problem.

due to my quick debug, the problem is somewhere into php_stripslashes
called on file.c:1543 i'll try to look into it on friday if this bug
still 'll be exists.

problem still exists on last cvs.

my editor show ascii(0) as ? but '\0' have to be showen as '\0'
mean, if the orginal text (c code this case) file included the \0
string i does't want fwrite() replace it with ascii(0)! but to save
it as the orginal string.

Please try using this CVS snapshot:

http://snaps.php.net/php4-STABLE-latest.tar.gz

For Windows:

http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

Cannot verify this bug with latest CVS. I think your editor just shows
\0 as ?

here is simple code:

<?
$f = fopen("test.txt","rb");
$buf= fread($f,4096);
$f2 = fopen("test2","wb");
fwrite($f2,$buf);
?>

where test.txt content is:
--------------test \0 test

the result test2 file is:

test ? test
