check for any content in php

Question

I want to see if there are any POST vars set. Is there anyway i can do this?

Answer 1

if (!empty($_POST)) {
    // handle post data
}

Answer 2

if(count($_POST) > 0) {
    // Post vars are set

Answer 3

Simple, $_POST is an array containing all POST vars, just count how any items are in the array and you know if there are any set.

echo count($_POST);
