How can PHP developers effectively handle escaping and quoting of search terms in database queries?

To effectively handle escaping and quoting of search terms in database queries, PHP developers should use prepared statements with placeholders instead of concatenating search terms directly into the query. This helps prevent SQL injection attacks and ensures that special characters in the search terms are properly escaped. 

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

// Prepare the query with a placeholder for the search term
$stmt = $pdo->prepare("SELECT * FROM table WHERE column = :search_term");

// Bind the search term to the placeholder and execute the query
$search_term = $_GET['search_term']; // Assuming the search term is coming from a form input
$stmt->bindParam(':search_term', $search_term);
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();
