How can PHP developers efficiently store and update search keywords in a database for faster search performance?

To efficiently store and update search keywords in a database for faster search performance, PHP developers can use a separate table to store the keywords along with a count of how many times each keyword has been searched. This allows for quick retrieval and updating of keyword information without impacting the main search performance. 

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=your_database", "username", "password");

// Function to update keyword count
function updateKeywordCount($keyword) {
    global $pdo;
    
    $stmt = $pdo->prepare("INSERT INTO keywords (keyword, count) VALUES (:keyword, 1) ON DUPLICATE KEY UPDATE count = count + 1");
    $stmt->bindParam(':keyword', $keyword);
    $stmt->execute();
}

// Function to retrieve search results based on keyword
function searchByKeyword($keyword) {
    global $pdo;
    
    $stmt = $pdo->prepare("SELECT * FROM search_results WHERE keyword = :keyword");
    $stmt->bindParam(':keyword', $keyword);
    $stmt->execute();
    
    return $stmt->fetchAll();
}
