Why is this using an random integer for the database id, shouldn’t the database decide on that? What if they clash? It’s not checking if it exists before attempting to use it, and anyway, why not just have SQL auto increment the ID? If you need to know the id for the encryption, (not that that’s a good idea), but you’d use mysql_insert_id(); to find out what auto increment value the database used.

Every part of your tutorial is really amateur coding, you should probably have mentioned that in your post somewhere, before others learn anything from it.

It depends on base-convert function and the number of digits you specify in the rand() function. Thanks.

I have implemented this all and I can write to the DB with shorten.php but when I put the shorted URL in I get:

Not Found

The requested URL /ltxh was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Apache/1.3.42 Server at sendnow.co Port 80

Any ideas on why?

When I shorten the url, go to the url, it says; Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/c0mmanet/public_html/url/decoder.php on line 19
