PHP Array Exercises : Create a two-dimensional array

Last update on December 20 2024 10:17:31 (UTC/GMT +8 hours)

Write a PHP script to create a two-dimensional array (4x4), initialized to 10.

Note: Use array_fill() function.

Sample Solution:

PHP Code:

<?php
// Create a multidimensional array filled with the value 10
// The outer array has 4 elements, and each element is an inner array
// The inner arrays have 4 elements each, all initialized with the value 10
$a = array_fill(0, 4, array_fill(0, 4, 10));

// Print the resulting multidimensional array
print_r($a);

?>

Output:

Array                                                       
(                                                           
    [0] => Array                                            
        (                                                   
            [0] => 10                                       
            [1] => 10                                       
            [2] => 10                                       
            [3] => 10                                       
        )
