How can PHP developers ensure data security by properly sanitizing input before storing it in a database?

To ensure data security, PHP developers should sanitize input data before storing it in a database to prevent SQL injection attacks. This can be achieved by using prepared statements with parameterized queries or by using functions like mysqli_real_escape_string() to escape special characters. By properly sanitizing input, developers can mitigate the risk of malicious code being injected into the database. 

// Example of sanitizing input before storing it in a database using prepared statements
$stmt = $pdo->prepare("INSERT INTO users (username, email) VALUES (:username, :email)");
$stmt->bindParam(':username', $username);
$stmt->bindParam(':email', $email);
$stmt->execute();
