How to create a Three Dimensional Array in PHP ?

Answer

To create a Three Dimensional Array in PHP, you can use nested arrays or array_fill() function.

✐ Examples

1 Creating a 3D Array with Nested Arrays

In this example,

We use nested arrays to create a 3D array with specified dimensions.
The first dimension represents the number of arrays, the second dimension represents the number of rows in each array, and the third dimension represents the number of elements in each row.

PHP Program

<?php 
// Creating a 3D Array with Nested Arrays
$threeDArray = [[[0, 0, 0, 0], [0, 0, 0, 0]], [[0, 0, 0, 0], [0, 0, 0, 0]], [[0, 0, 0, 0], [0, 0, 0, 0]]];
// Accessing and modifying elements
$threeDArray[1][0][2] = 5;
// Printing the array
print_r($threeDArray);
?>

Output

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

            [1] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

        )

    [1] => Array
        (
            [0] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 5
                    [3] => 0
                )

            [1] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

        )

    [2] => Array
        (
            [0] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

            [1] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

        )
