Are there any specific functions in PHP that can help in reordering elements within a multidimensional array?

To reorder elements within a multidimensional array in PHP, we can use the `array_multisort()` function. This function can sort multiple arrays or multidimensional arrays based on one or more key values. By specifying the key we want to sort by and the sorting order, we can easily rearrange the elements within the multidimensional array. 

// Sample multidimensional array
$students = array(
    array('name' => 'Alice', 'age' => 20),
    array('name' => 'Bob', 'age' => 22),
    array('name' => 'Charlie', 'age' => 21)
);

// Sort the array by 'age' in ascending order
array_multisort(array_column($students, 'age'), SORT_ASC, $students);

// Print the sorted array
print_r($students);
