PHP Array

A PHP array can be thought of as a variable which can store multiple other variables. Every item in a PHP array is known as an element and is composed of a key and a value. There are 2 main types of PHP arrays:

1. Numeric Array
2. Associative Array

Each of these can in turn be a Multidimensional Array.

Example Numeric Array:

$terms = array('array', 'element', 'key', 'value');
var_dump($terms);
/* => Array
(
    [0] => array
    [1] => element
    [2] => key
    [3] => value
)
*/

Example Associative Array:

$terms = array(
	'term1' => 'array', 
	'term2' => 'element', 
	'term3' => 'key', 
	'term4' => 'value'
);
var_dump($terms);
/* => Array
(
    [term1] => array
    [term2] => element
    [term3] => key
    [term4] => value
)
*/
