Elements of an array are accessed using a key. There are two types of array depending on the type of key that is used to access an array element. In a numerical key array elements are accessed by specifying the numerical position of the item in the array. The first item in an array is element 0, the second is element 1 and so on. The second type of array is the ''associative array'' where a name is given to each element and that name is used to access the corresponding array element.

Arrays are created using the ''array()'' function. ''array()'' function takes zero or more arguments and retruns the new array which must be assigned to a variable using the assigment operator. If arguments are provided they are used to initialize the array with data.
