php encryption program

//Encryption
function jiami($data,$psw){
for($i=0,$j=0;$i              $middle = ord(substr($data,$i,1)) +
            ord(substr($psw,$j,1));
If ($j > strlen($psw)){
$j=0;
}
              $str .=chr($middle);
}
Return($str);
}
//Decrypt
function jiemi($data,$psw){
for($i=0,$j=0;$i               $middle = ord(substr($data,$i,1)) -
            ord(substr($psw,$j,1));
If ($j > strlen($psw)){
$j=0;
}
              $str .=chr($middle);
}
Return($str);
}
?>
