What are some best practices for sorting arrays in PHP while maintaining relationships between elements?

When sorting arrays in PHP while maintaining relationships between elements, one approach is to use a custom sorting function that considers the relationships between elements. This can be achieved by creating a multidimensional array where each sub-array contains the original element and its corresponding relationship. Then, the usort() function can be used to sort the array based on the relationships. 

// Sample array with relationships
$originalArray = [
    ['element' => 'A', 'relationship' => 2],
    ['element' => 'B', 'relationship' => 1],
    ['element' => 'C', 'relationship' => 3],
];

// Custom sorting function based on relationships
usort($originalArray, function($a, $b) {
    return $a['relationship'] <=> $b['relationship'];
});

// Output the sorted array
print_r($originalArray);
