david method (27-May-2004 02:50) is very collision. Example:
<?php
echo ftok('C:\file.php', 'a'); // 450
echo ftok('C:\life.php', 'a'); // 450
echo ftok('C:\feli.php', 'a'); // 450
?>
On Windows I use my code:
<?php
if(!function_exists('ftok')) {
function ftok($pathname, $proj) {
if(false === ($pathname = realpath($pathname))) {
return -1;
}
$proj = ord($proj);
extract(unpack('iresult', md5($pathname, true)));
return ($result ^ $proj);
}
}
?>
