What best practices should be followed when designing a PHP script to handle asynchronous requests for search results without reloading the page?

When designing a PHP script to handle asynchronous requests for search results without reloading the page, it is best to use AJAX to send the request to the server and update the search results dynamically. This can be achieved by creating a separate PHP script that handles the search query and returns the results in JSON format. The client-side JavaScript code can then process the JSON response and update the search results on the page without a full page reload. 

<?php
// search.php

// Process the search query
$searchQuery = $_GET['query'];
// Perform the search logic here

// Return the search results in JSON format
header('Content-Type: application/json');
echo json_encode($searchResults);
?>
