What is the potential issue with using the SQL LIKE operator in PHP queries?

The potential issue with using the SQL LIKE operator in PHP queries is the risk of SQL injection attacks if user input is not properly sanitized. To solve this issue, it is important to use prepared statements with bound parameters to securely handle user input in SQL queries. 

// Using prepared statements to securely handle user input in SQL queries
$searchTerm = $_POST['searchTerm'];

// Prepare a SQL statement with a placeholder for the search term
$stmt = $pdo->prepare("SELECT * FROM table_name WHERE column_name LIKE :searchTerm");

// Bind the search term parameter to the placeholder
$stmt->bindParam(':searchTerm', $searchTerm, PDO::PARAM_STR);

// Execute the prepared statement
$stmt->execute();

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