4.5. Brief Introduction to Variable Types

Variables in PHP can be of type integer (a whole number), floating-point (usually called "float"; a fractional number), string (a set of characters), array (a group of data), object (a complex mix of data and functionality), or a resource (any external information, such as an image).
