How to create and set values to a 3d array in PHP

Answer 1

function initializeArray(&$array, $x, $y, $z) {
    for ($i = 0; $i < $x; $i++) {
        for ($j = 0; $j < $y; $j++) {
            for ($k = 0; $k < $z; $k++) {
                $array[$i][$j][$k] = $i + $j + $k; // Initialization
            }
        }
    }
}

function printArray($array, $x, $y, $z) {
    for ($i = 0; $i < $x; $i++) {
        for ($j = 0; $j < $y; $j++) {
            for ($k = 0; $k < $z; $k++) {
                echo $array[$i][$j][$k] . " ";
            }
            echo "\n";
        }
    }
}

$x = 2;
$y = 3;
$z = 4;
$array = array_fill(0, $x, array_fill(0, $y, array_fill(0, $z, 0))); // Create a 3D array

initializeArray($array, $x, $y, $z);
printArray($array, $x, $y, $z);
