Are there best practices for efficiently sorting multidimensional arrays in PHP to avoid performance issues?

When sorting multidimensional arrays in PHP, it's important to use efficient sorting algorithms to avoid performance issues, especially with large datasets. One common approach is to use the `usort()` function along with a custom comparison function to sort the array based on specific criteria. Additionally, you can optimize the sorting process by avoiding unnecessary array manipulation within the comparison function. 

// Example of efficiently sorting a multidimensional array in PHP
$data = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

usort($data, function($a, $b) {
    return $a['age'] - $b['age']; // Sort by age in ascending order
});

print_r($data);
