In PHP, how do I sort objects in a high-traffic application?

Sorting objects in a high-traffic PHP application can significantly improve performance and maintainability. Utilize built-in functions such as `usort` or `array_multisort` for efficient sorting. Pay attention to the data structure and sorting algorithm to ensure optimal performance.

Here's an example of sorting an array of objects based on a specified property:

<?php class Product { public $name; public $price; public function __construct($name, $price) { $this->name = $name; $this->price = $price; } } $products = [ new Product("Product A", 30), new Product("Product B", 20), new Product("Product C", 25), ]; usort($products, function($a, $b) { return $a->price - $b->price; }); foreach($products as $product) { echo $product->name . ': $' . $product->price . '<br>'; } ?>
