PHP: Arrays

Arrays in PHP

There are three types of arrays in PHP:

1. Indexed array
2. Associative array
3. Multidimensional array

Example: Simple One Dimensional, Indexed PHP Array

Array elements in this type of array are accessed through a numeric key, e.g. 0, 1, etc.

	<?php
	$artists = array("Elton John", "Eric Clapton", "Sam Cooke", "Prince");
	echo "<p>My favorite artist is " . $artists[3] . "</p>.";
	?>
