The following example creates an indexed array of movie director names and stores it in a variable called $directors: To create an indexed array, just list the array values inside the parentheses, separated by commas. To create an array, you use the array() construct: It’s easy to create an array within a PHP script. Furthermore, many PHP array functions are designed to work with either indexed or associative arrays.Īn associative array is sometimes referred to as a hash, and its indices are often called keys. Most of the time, however, it helps to think of indexed and associative arrays as different types of arrays. You can even mix numeric and string indices within the same array if you like. In fact, PHP doesn’t make any internal distinction between indexed and associative arrays. Typically, you use an associative array when you want to store records of data, much like using a database. The order of the elements is usually unimportant. For example, one element of an associative array might have an index of "name", while another element has an index of "age". A ssociative arrays have string indices.Usually, you use an indexed array when you want to store a bunch of data in a certain order. Typically the indices in an indexed array start from zero, so the first element has an index of 0, the second has an index of 1, and so on. For example, you can sort array elements quickly and easily search arrays for particular values or indices and merge arrays together. PHP gives you many handy array-related functions.You can easily loop through all elements in an array, reading or changing each element’s value as you move through the loop. It’s easy to work with many values at once. It’s easy to add or remove elements in an array, as well as read or change the value of an element. This allows you to create multidimensional arrays.Īrrays in PHP offer many benefits, including the following: An array element’s value can itself be an array.An array’s length is the number of elements in the array.You can mix types within an array - for example, the first element can contain an integer, the second can contain a string, and so on.
