// 

$theMD5 = md5("ayht" . $_POST["rn"] . "thy", 1);



$hexArr[0] = "0";

$hexArr[1] = "1";

$hexArr[2] = "2";

$hexArr[3] = "3";

$hexArr[4] = "4";

$hexArr[11] = "B";

$hexArr[12] = "C";

$hexArr[13] = "D";

$hexArr[14] = "E";

$hexArr[15] = "F";

        

for($i=0;$i<strlen($theMD5);$i++)

{

        $tmp1 = ord($theMD5[$i]) / 16;

        $tmp2 = ord($theMD5[$i]) % 16;



        $theHash = $theHash. $hexArr[$tmp1] . $hexArr[$tmp2];

}



$theHash = strtolower($theHash);



echo $theHash;

?>

Is there a simple fix to this please?

Re: HELP: Undefined variable
 

Set $theHash equal to empy before the for loop.
Also, I think you'll want to poulate $theHash like this:

$theHash="";

for($i=0;$i<strlen($theMD5);$i++)

{

        $tmp1 = ord($theMD5[$i]) / 16;

        $tmp2 = ord($theMD5[$i]) % 16;



        $theHash.= $hexArr[$tmp1] . $hexArr[$tmp2];

}
