[PHP-DEV] PHP 4.0 Bug #7987 Updated: POST/GET: string with NULL values not parsed correctly From: andbe611 <email protected>

Description: POST/GET: string with NULL values not parsed correctly

Ok, I found this in:
php_variables.c row 202
/* FIXME: XXX: not binary safe, discards returned length */
php_url_decode(var, strlen(var));
php_url_decode(val, strlen(val));
php_register_variable(var, val, array_ptr ELS_CC PLS_CC);

So I guess you are already aware of the problem.

Here is a short script that shows the problem. (I guess I should have posted thins in my first bugreport, sorry)
The script null_string.php gets called with:
http://myserver.com/null_string.php?truncated=hello%00world

null_string.php:
<?php
$works= "hellox00world";
$fp = fopen("file.txt","w");
fwrite($fp,"$worksn");
fwrite($fp,"$truncatedn");
fclose($fp);
?>

file.txt opened in an hex editor:

hex: 68 65 6C 6C 6F 00 77 6F-72 6C 64 0A 68 65 6C 6C 6F 0A
text:hello.world.hello.

The $works is saved with the null value, but the $truncated in the get request gets truncated by php.

are you sure they get truncated?
please echo strlen($HTTP_POST_VARS["var"]) *before* the
other output and please don't use NS 4.x it is known to
truncate an unknown number of bytes after a
