PHP Array Exercises : Create a two-dimensional array
56. Create Two-Dimensional Array (4x4) Initialized to 10
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
)
[1] => Array
(
[0] => 10
[1] => 10
[2] => 10
[3] => 10
)
[2] => Array
(
[0] => 10
[1] => 10
[2] => 10
[3] => 10
)
[3] => Array
(
[0] => 10
[1] => 10
[2] => 10
[3] => 10
)
)
