php - How to detect if $_POST is set?

Question

I want to know how to detect if $_POST is set or not.

Right now I detect it like this:

if(isset($_POST['value']))

But I'm not looking if value is set anymore. Basically, any POST will work.

if(isset($_POST))

I'm not sure how PHP handle this. Perhabs isset($_POST) is always returns true since it's a PHP global?

Basically, how can I do this?

Try with:

if ( $_SERVER['REQUEST_METHOD'] == 'POST' ) {}

to check if your script was POSTed.

If additional data was passed, $_POST will not be empty, otherwise it will.

You can use empty method to check if it contains data.

if ( !empty($_POST) ) {}
