DevShed:
Building a Data Validation System with the Prototype Pattern with PHP 5
May 23, 2007 @ 15:43:00

DevShed has posted the last part of their latest series, a look at using the Prototype pattern in a PHP5 application, Building a Data Validation System with the Prototype Pattern with PHP 5.

Taking into account that this pattern can be helpful in situations where a prototype object is required, along with other clones of it, in this final installment of the series I'm going to demonstrate how to use it to build a simple application for checking the validity of incoming data.

They create a simple validation system with the pattern to check and see if the inputted data is either alpha only or alpha-numeric. On top of this, they create some additional classes to check the data for things like being a valid email address or if the value is made up of all numbers.
