identifier

My application requires the user to enter their business name, which the application will automatically create into a unique identifier to be used in URLs, ie

"Bob's Cafe" will become "bobs-cafe"

But if there are duplicate names I would like the application to add a number so if there is already a "bobs-cafe" we will use "bobs-cafe-1" and likewise if there is already a "bobs-cafe-1" we will use "bobs-cafe-2"

Ive used explode and also looked at a regular expressions but I dont know the best way to approach this.

Im stuck in being able to grab the number and incrementing it and returning the string

If I do ... $code = sha1($id); ... and then store $code into the same row as $id. Will my code column be unique as well… >>> More
