What potential pitfalls should be avoided when using the $HTTP_POST_VARS variable in PHP?

Avoid using the deprecated $HTTP_POST_VARS variable in PHP as it can lead to security vulnerabilities such as injection attacks. Instead, use the $_POST superglobal array to access POST data securely. 

// Use $_POST superglobal array instead of $HTTP_POST_VARS
if(isset($_POST['username'])) {
    $username = $_POST['username'];
    // Process the username securely
}
