Description:
------------
Hi I am using latest version of PHP-FPM from and nginx
deb https://packages.sury.org/php/ stretch main

When my URL is for example
http://server.url/test.php?test=%00123456789

then the result is: 
Array ( [test] => 123456789 ) 

and not
Array ( [test] => %00123456789 ) 

PHP will interpret beginning of the string as a hex 0x00


Test script:
---------------
<?php
print_r($_GET);

?>

Expected result:
----------------
Array ( [test] => %00123456789 )

Actual result:
--------------
Array ( [test] => 123456789 )
