I get input from user through a form and then process.
For example,
Method 1:

if $_POST[\'submit\']{
$title = $_POST[\'title\'];
$message = $_POST[\'message\'];

send_message($title, $message);
}

Now

function send_message($title, $message){
$t= secure($title);
$m = secure($message);

---
--
}

Method 2:

if $_POST[\'submit\']{

$title = secure($_POST[\'title\']);
$message = secure($_POST[\'message\']);

send_message($title, $message);
}

function send_message($title, $message){
//no need to secure input here as i already did before passing to this function.
}

Please note that in method 1 i did not secure the input, i sent the input as the user submitted it. I will secure it in the send_message function before i insert to database.
in Method 2, I first of all secured input and then passed to the function.

So my question is that, is there any security risk by passing the inputs in a function as above?

Should i secure the inputs before i call the send_message function?
Which of the method is more secure?
