How to pass 2D array (matrix) to function in PHP

Answer 1

function print_array($arr)
{
    $rows = count($arr);
    $cols = count($arr[0]);
    
    for ($i = 0; $i < $rows; $i++) {
        for ($j = 0; $j < $cols; $j++)
            echo $arr[$i][$j] . " ";
        echo "<br />\n";
   }
}

$arr = array(
    array(11, 32, 13),
    array(20, 80, 990),
);

print_array($arr);



/*
run:

11 32 13 
20 80 990  
   
*/
