What are common pitfalls to avoid when integrating PHP scripts with HTML forms for dynamic content?

One common pitfall to avoid when integrating PHP scripts with HTML forms for dynamic content is not properly sanitizing user input, which can leave your application vulnerable to security risks such as SQL injection attacks. To solve this issue, always use functions like htmlspecialchars() or mysqli_real_escape_string() to sanitize user input before using it in your PHP scripts. 

// Example of sanitizing user input using htmlspecialchars()
$name = htmlspecialchars($_POST['name']);
$email = htmlspecialchars($_POST['email']);

// Example of sanitizing user input using mysqli_real_escape_string()
$conn = mysqli_connect("localhost", "username", "password", "database");
$name = mysqli_real_escape_string($conn, $_POST['name']);
$email = mysqli_real_escape_string($conn, $_POST['email']);
