How to define a two-dimensional array in php

How to define a two-dimensional array in php?

The values ​​in one array can be another array, and the values ​​in another array can also be an array. In this way, we can create a two-dimensional or three-dimensional array:

The code example is as follows:

<?php
// 二维数组:
$cars = array
(
    array("Volvo",100,96),
    array("BMW",60,59),
    array("Toyota",110,100)
);
print_r($cars);
?>

Output:

Array
(
    [0] => Array
        (
            [0] => Volvo
            [1] => 100
            [2] => 96
        )

    [1] => Array
        (
            [0] => BMW
            [1] => 60
            [2] => 59
        )

    [2] => Array
        (
            [0] => Toyota
            [1] => 110
            [2] => 100
        )
