How can iterators be used effectively to manage arrays in PHP, especially when dealing with multidimensional arrays?

When dealing with multidimensional arrays in PHP, iterators can be used effectively to traverse through the arrays and perform operations on each element. By using iterators like foreach or while loops, you can easily access and manipulate the elements of multidimensional arrays without needing to know the exact structure or dimensions of the array. 

// Example of using iterators to manage a multidimensional array in PHP
$multiArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

// Using foreach loop to iterate through the multidimensional array
foreach($multiArray as $innerArray){
    foreach($innerArray as $element){
        echo $element . " ";
    }
    echo "<br>";
}
