What potential security risks are associated with using HTTP_POST_VARS in PHP?

Using HTTP_POST_VARS in PHP can pose security risks such as vulnerability to injection attacks and data manipulation. To mitigate these risks, it is recommended to use the $_POST superglobal array instead, as it is more secure and reliable. 

// Using $_POST superglobal array instead of HTTP_POST_VARS
if(isset($_POST['username'])){
    $username = $_POST['username'];
    // Perform necessary operations with $username
}
