note 33940 added to function.levenshtein

I am using this function to avoid duplicate information on my client's database. After retrieving a series of rows and assigning the results to an array values, I loop it with foreach comparing its levenshtein() with the user supplied string. It helps to avoid people re-registering "John Smith", "Jon Smith" or "Jon Smit". Of course, I can't block the operation if the user really wants to, but a suggestion is displayed along the lines of: "There's a similar client with this name.", followed by the list of the similar strings. ---- Manual Page -- http://www.php.net/manual/en/function.levenshtein.php Edit Note -- http://master.php.net/manage/user-notes.php?action=edit+33940 Delete Note -- http://master.php.net/manage/user-notes.php?action=delete+33940&report=yes Reject Note -- http://master.php.net/manage/user-notes.php?action=reject+33940&report=yes
