How can the use of addslashes() in PHP impact the security and functionality of a search feature?

Using addslashes() in PHP can impact the security and functionality of a search feature by potentially allowing SQL injection attacks. Instead, it is recommended to use prepared statements with parameterized queries to prevent malicious input from affecting the database queries. 

// Using prepared statements to prevent SQL injection
$searchTerm = $_GET['searchTerm'];
$stmt = $pdo->prepare("SELECT * FROM products WHERE name = :searchTerm");
$stmt->bindParam(':searchTerm', $searchTerm);
$stmt->execute();
$results = $stmt->fetchAll();
