Are there any potential security risks involved in using PHP-integrated SQL queries to manipulate databases?

Using PHP-integrated SQL queries can potentially lead to SQL injection attacks if input data is not properly sanitized or validated. To mitigate this risk, it is recommended to use prepared statements with parameterized queries, which separate SQL logic from user input data, preventing malicious SQL code from being executed. 

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

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

// Bind the parameter value
$stmt->bindParam(':username', $_POST['username']);

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

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