An integer is a whole number, sometimes referred to as a "counting number." For instance, the number 5 is an integer. As is 19 and -2289. 0 is an integer.
Integers do not have a fractional part. In PHP, those numbers are called floats. So 1.4, -34.873, and PI are all floats.
Because PHP is weakly typed, there's not as much concern as in other languages. If you try an do something mathematically to a number you declared as an integer that requires it to be a float, PHP almost always makes the implicit conversion between the two types. The same goes for when you try to print and integer of a float on the screen: PHP will convert them into strings without your having to lift a finger.
