What are common pitfalls when integrating PHP scripts and how can they be avoided?

One common pitfall when integrating PHP scripts is not properly sanitizing user input, which can leave your application vulnerable to security risks such as SQL injection attacks. To avoid this, always use prepared statements when interacting with a database to prevent malicious input from being executed as SQL queries. 

// Example of using prepared statements to avoid SQL injection

// Assuming $conn is a valid database connection

$stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
$stmt->bind_param("s", $username);

$username = $_POST['username'];
$stmt->execute();
$result = $stmt->get_result();

while ($row = $result->fetch_assoc()) {
    // Process the retrieved data
}

$stmt->close();
