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.
The te-edu Password Meter class can be used to check whether a password is strong enough to not be guessed easily. It can perform several tests on a given password string to compute a score that represents the strength of a password. Password checking is based on brute force attack class A and considers 10 million password checks in one minute. It checks characters, character pairs, repeated characters, time needed to be discovered, character standard entropy, etc.
