Are there any security concerns to be aware of when dynamically generating PHP content from MySQL in PHP?

When dynamically generating PHP content from MySQL in PHP, there is a security concern known as SQL injection. To prevent this, you should always use prepared statements with parameterized queries to sanitize user input and prevent malicious SQL queries. 

// Establish a connection to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM users WHERE username = :username");

// Bind the parameter and execute the query
$stmt->bindParam(':username', $username);
$stmt->execute();

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