![]() 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. The first item in an array is element 0, the second is element 1 and so on. In a numerical key array, elements are accessed by specifying the numerical position of the item in the array. There are two types of array, and the type of key that is used to access an array element dictates the array type. The items in an array can be of any variable type, and an array can contain any mixture of data types - it is not necessary to have each element in the array of the same type.Įlements of an array are accessed using a key. Once an array has been created items can be added, removed and modified, sorted and much more. An array is, in many ways, a self-contained list of variables. PHP Arrays provide a way to group together many variables such that they can be referenced and manipulated using a single variable.
