In PHP, JavaScript, ECMAScript, ActionScript 3.0, and a number of other similar, dynamic languages, there are two types of equality checks: == (non-strict equality) and === (strict equality). To show an example:
Basically, whenever you use ==, you risk automatic type conversions. Using === ensures that the values are logically equal AND the types of the objects are also equal.
