PHPDevel Link Checker is a PHP script to check Web sites for broken links, invalid URLs, missing MIME, charset, titles, descriptions, canonical URLs, and more.

NORM is a simple ORM for PHP. It works with PDO and MySQL. Unlike other ORMs, NORM is neither complicated, convoluted, nor daunting. You can easily throw a regular object at NORM, tie in a couple other objects to relate to it, store it in a database, and return it as a regular associative array or regular object that you can toss into JSON output or a template. It lets you create and store your objects without worrying about SQL, since NORM takes care of building and managing database tables.
