How can multidimensional arrays be effectively output in PHP?

To effectively output multidimensional arrays in PHP, you can use nested loops to iterate through the arrays and display the elements. By using a combination of foreach loops and conditional statements, you can access and display the values of the nested arrays in a structured format. 

$multiArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

foreach ($multiArray as $array) {
    foreach ($array as $value) {
        echo $value . " ";
    }
    echo "<br>";
}
