What is the best practice for iterating through multidimensional arrays in PHP?

When iterating through multidimensional arrays in PHP, it is best practice to use nested loops to traverse through each level of the array. This allows you to access and manipulate the elements of the array effectively. 

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

foreach ($multiArray as $innerArray) {
    foreach ($innerArray as $value) {
        echo $value . " ";
    }
}
