Re: How can I check for variances in spelling within form text input fields?

Don I am not a 'PHP guru' and I dont know where you can find an algorithm but:- If the only problem is users adding/not using name extensions, then for your company exists already test you could remove known extensions from the input company name - ltd, plc, etc - and replace this with a wildcard for the check. eg. SELECT id FROM table WHERE name LIKE '$input_name_without_extensions%' Debbie ----- Original Message ----- From: "DonPro" <donpro@lclcan.com> To: "php list" <php-general@lists.php.net> Sent: Wednesday, October 02, 2002 4:27 PM Subject: [PHP] How can I check for variances in spelling within form text input fields? > Hi, > > I would like some ideas on how to perform the following.
