help with md5

[Jnerocorp]

Hello,

 

I have this script

<?php
      function getUniqueCode($length = "6")
      {
    $characters = "!@$%^&*()-==_[]\{}|;':,./<>?0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
$string = $characters[mt_rand(0, $characters)];

      $code = md5(uniqid("$string", true));
      if ($length != "") return "<b>String</b>: $string == <b>MD5</b>:" . substr($code, 0, $length) ."";
      else return "<b>String</b>: $string == <b>MD5</b>:" . $code ."";
      }
  echo getUniqueCode();
?>

 

and its displaying:

 

String: ! == MD5:2ecd4a

 

the ! is supposed to be where the string is that was turned into an md5

 

can anyone please help with this?

i think here

$string = $characters[mt_rand(0, $characters)];

 

you want it to be

$string = $characters[mt_rand(0, count($characters))];

 

right now that basically looks like

$string = $characters[mt_rand(0,"!@$%^&*()-==_[]\{}|;':,./<>?0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ" )];

 

which doesn't really make sense

now its doing

 

String: ! == MD5:4ec75b

and

String: @ == MD5:wm3d4d

 

but the md5 always changes  to something new

[mikesta707]

what should it be? that is exactly what your code should be doing.

 

$string = $characters[mt_rand(0, count($characters))];

 

that will store a single character (a random one) into the $string variable. what do you want your code to do?
