How can PHP developers integrate Ajax queries with PDO for live search functionality?

To integrate Ajax queries with PDO for live search functionality in PHP, developers can create a PHP script that connects to a database using PDO to retrieve search results based on user input. This script can be called asynchronously using Ajax to update search results in real-time without refreshing the page.

<?php
// Include database connection file
include 'db_connection.php';

// Get search term from Ajax request
$searchTerm = $_GET['searchTerm'];

// Prepare SQL statement to search for matching records
$stmt = $pdo->prepare("SELECT * FROM products WHERE name LIKE :searchTerm");
$stmt->bindValue(':searchTerm', '%' . $searchTerm . '%');
$stmt->execute();

// Fetch and return search results as JSON
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($results);
