What are the consequences of neglecting SQL injection prevention measures in PHP applications, even if security concerns are addressed later?

Neglecting SQL injection prevention measures in PHP applications can lead to severe security vulnerabilities, allowing attackers to manipulate databases, steal sensitive information, or even take control of the entire system. Even if security concerns are addressed later, the damage caused by a successful SQL injection attack can be significant. It is crucial to implement proper input validation and parameterized queries to prevent SQL injection attacks. 

// Implementing SQL injection prevention measures using parameterized queries
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM users WHERE username = :username');
$stmt->bindParam(':username', $_POST['username']);
$stmt->execute();
$results = $stmt->fetchAll();
