Issue: How to prevent SQL injection attacks in PHP by using prepared statements. To prevent SQL injection attacks in PHP, it's important to use prepared statements when interacting with a database. Prepared statements separate SQL code from user input, making it impossible for an attacker to inject malicious code into the query. This technique ensures that user input is treated as data, not executable code. 

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

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

// Bind the user input to the placeholder
$stmt->bindParam(':username', $username);

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

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