What are some common security concerns when implementing dynamic links in PHP?

One common security concern when implementing dynamic links in PHP is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, always use prepared statements with parameterized queries when interacting with a database. 

// Example of using prepared statements to prevent SQL injection

// Assuming $conn is the database connection object

$stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);

$username = $_GET['username'];
$stmt->execute();

// Rest of the code to fetch and process the data
