This document discusses the different types of arrays in PHP. There are three main types: numeric arrays which use numeric indices, associative arrays where each key is associated with a value, and multi-dimensional arrays which contain one or more nested arrays. Examples are provided for each type to demonstrate how to define and access array elements.
![Numeric Array
An array with numeric index.
$student = array(abc=>123, xyz, ccc);
for($x=0; $x < sizeof($student); $x++)
{
echo $student[$x].<br>;
