Are there any best practices for handling multidimensional arrays in PHP, especially when sorting by specific values?

When handling multidimensional arrays in PHP and sorting by specific values, it is important to use the `usort()` function along with a custom comparison function. This allows you to define the sorting criteria based on specific values within the multidimensional array. 

// Sample multidimensional array
$users = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

// Custom comparison function to sort by age
usort($users, function($a, $b) {
    return $a['age'] <=> $b['age'];
});

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