How can PHP be utilized to improve the search functionality of a website?

One way to improve the search functionality of a website using PHP is by implementing a search algorithm that allows users to search for specific keywords or phrases within the website's content. This can be achieved by creating a search form where users can input their search queries, and then using PHP to process the input and retrieve relevant results from the website's database. By implementing a robust search algorithm in PHP, users can easily find the information they are looking for on the website. 

// PHP code snippet for implementing search functionality

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Process search query
if(isset($_GET['search'])) {
    $search = $_GET['search'];

    // Perform search query
    $sql = "SELECT * FROM articles WHERE title LIKE '%$search%' OR content LIKE '%$search%'";
    $result = $conn->query($sql);

    // Display search results
    if ($result->num_rows > 0) {
        while($row = $result->fetch_assoc()) {
            echo "Title: " . $row["title"]. " - Content: " . $row["content"]. "<br>";
        }
    } else {
        echo "No results found";
    }
}

// Close database connection
$conn->close();
