md5 php script

Hello, Can someone change this script

 $hash = "9bf31c7ff062936a96d3c8bd1f8f2ff3";
$char[1] = "0";
$char[2] = "1";
$char[3] = "2";
$char[4] = "3";
$char[5] = "4";
$char[6] = "5";
$char[7] = "6";
$char[8] = "7";
$char[9] = "8";
$char[10] = "9";
$top = count($char);
For ($d = 0; $d <= $top; $d++)
{
$ad = $ae.$char[$d];
for ($c = 0; $c <= $top; $c++)
{
$ac = $ad.$char[$c];
for ($b = 0; $b <= $top; $b++)
{
$ab = $ac.$char[$b];
for ($a = 0; $a <= $top; $a++)
{
$aa = $ab.$char[$a];
if(md5($aa)==$hash)
{
die('Wachtwoord: '.$aa);
}
}
}
}
}	
	

Code (markup):

in particular

die('Wachtwoord: '.$aa); 

Code (markup):

I want to be the outcome variable.
instead

die('Wachtwoord: '.$aa);

Code (markup):

of being example $a = .$aa



when away

die('Wachtwoord: '.$aa);

Code (markup):

results began to be repeated many times and there is my problem

 

Are aware that php has built in functions for encryption including md5?

http://php.net/manual/en/function.md5.php and also more advanced ones such as SHA, and rijndael-256 http://php.net/manual/en/function.mcrypt-module-open.php

krisx idea is better cause it lets you use a salt.

 

Technically an almost foolproof way would be to use md5(md5(str) . salt) . it prevents the hash from being tested against md5 tables.
