What are the potential risks of using the LIKE operator in MySQL queries within a PHP application?

Using the LIKE operator in MySQL queries within a PHP application can expose the application to SQL injection attacks if user input is not properly sanitized. To mitigate this risk, it is important to use prepared statements with parameterized queries to prevent malicious input from being executed as SQL code. 

// Using prepared statements with parameterized queries to prevent SQL injection

$pdo = new PDO('mysql:host=localhost;dbname=my_database', 'username', 'password');

$searchTerm = $_POST['searchTerm'];

$stmt = $pdo->prepare("SELECT * FROM table WHERE column LIKE :searchTerm");
$stmt->bindParam(':searchTerm', $searchTerm, PDO::PARAM_STR);
$stmt->execute();

// Fetch and process results
