How to make letters from numbers

I would like to change number (ie. 19455) into something shorter using numbers and digits (ie. w3b) so for example number 19455 is replaced by w3b. I would like to be able to get back that number when I enter w3b. Is there a ready function that I could use or do I have to build it by myself?

I hope this will do...

     <?
     # MAKE STRING INTO ARRAY TO FOR NUMBERS 0-9
   $numbers = array();
   for($counter =0; $counter <= 10; $counter++) {
       $numbers[$counter] = $counter;
    }


                 # FUNCTION TO CHANGE NUMBER INTO LETTERS
     function change_to_letters($string) {
    global $numbers;
  $replacements = array("a","b","c","d","e","f","g","h","i","j");
     $string = str_replace($numbers, $replacements, $string);
  return $string;
 }
     if(isset($_POST['submit'])){
    echo 'I changed '.$_POST['string'].' to this:<div style="border: 1px solid          #666;background-  color:                                                                #E6FAD9;width:200px;padding:5px;">'.change_to_letters($_POST['string']).'</div>';
          }

          ?>

   <!-- INPUT FORM --->
         <form action="" method="post">
           Enter some numbers here and i will change them into letters:<br /><input           name="string" type="text" size="15" maxlength="10"><br />
     <input type="submit" name="submit" value="Convert"><br />
     </form>

Use base_convert php function:

Example:

$myNumInDecimal = "1234567787";
$myNumInBase36 = base_convert($myNumInDecimal, 10, 36);

this will give you:

BUT notice that both to and from bases should be between 2..36.

Sounds like you're looking for str_replace

Try to a function that convert your number which are in decimal to hexadecimal , that will make a good solution I guess
