SitePoint PHP Blog:
Zend_Filter Reviewed, Blacklist / Whitelist Filters
March 28, 2006 @ 18:20:37

The Zend Framework has definitely made a huge splash in the PHP community, and everyone is picking their piece of it to cover. In this new post from the SitePoint PHP blog, Maarten Manders highlights the Zend_Filter module.

I like Zend Framework's Zend_Filter class. It's basically a set of methods for validating untrusted data. Although the two arguably most important features isEmail() and isUri() (the latter can be worked around with Zend_Uri) are still missing, the whole thing looks promising already.

He starts with a few of his thoughts on the package ("Clean up the code of isHostname", "International support for isPhone") and some code to show how it can be implemented - filtering for use in a regular expression, validation of a string by a character whitelist as well as blacklisting, and using the Zend_Filter module for a more flexible isName.
