sth like:

3 ewdsiq

I am unsure if you wish to use existing function, this should provide a non-hexadecimal only hash.

<?php
$nums = array(1, 2, 3, 4, 5);

foreach($nums as $num)
    echo "$num " ,  substr(strtolower(base64_encode(sha1($num))),0,6) . "\n";

Does it work for how many number?
I want to change serial number to string but short one.
Note I have 3 field which should give me one hash!
Table strut
sid (Number that I want change it to string)
type (A Number between 20 number)
Name (String)
SN (String)

You can simply concatenate the fields and pass it through my sha1 set of functions. It will work for any length string and return a short string out of it.

Can you show how?
I don't know how to use it!

All you need to do is make the query, and return the results, and combine them. A simple example:

function doHash($string) {
    return substr(strtolower(base64_encode(sha1($string))), 0, 6);
}

$hashstr = "";

$query = mysql_query("SELECT (sid, type, Name, SN) FROM strut WHERE (...) ");
while($row = mysql_fetch_assoc($query) {
   $hashstr = doHash($row['sid'] . $row['type'] . $row['Name'] . $row['SN']);
}

echo $hashstr;

Is that what you wanted?

yes,
This what I need!
