//manually
$cars = array();
$cars[0] = "one";
$cars[1] = "two";
$cars[3] = "three";
print_r($cars);
?>
</body>
</html>
Multidimensional Array :
- A multidimensional array in PHP is an array that contains other arrays as its elements. It allows you to store and organize data in multiple dimensions, forming a grid-like structure.
- Each element in a multidimensional array can itself be an array, creating a nested structure.
- To create a multidimensional array in PHP, you can use square brackets to define the array and separate the elements with commas. Here's an example of a 2-dimensional array:

<!DOCTYPE html>
<html>
<body>
<?php
//automatically
$matrix = array("a"=>array("a1","a2","a3"),"b"=>array("b1","b2","b3"),"c"=>array("c1","c2","c3"));
print_r($matrix);
//manually
$array = array([1,2,3],[4,5,6],[7,8,9]);
$array[0][1]."<br>";
$array[1][1]."<br>";
$array[2][1]."<br>";
$array[3][1];
