Building a More Capable Validation Helper Class
August 24, 2009 @ 13:16:47

DevShed continues their series on helpers classes in PHP applications with the sixth part of the series focusing on updates to their Validation class to add additional format checks.

It would be really useful to add more methods to it to validate other things, like email and IP addresses, to mention just two examples. Thus, in the next few lines I'm going to extend the abilities of this helper class so it can be used to perform the validation processes mentioned above.

They include the code that lets you validate URLs, IP addresses and email addresses for correctness via PHP's filter_var function.
