Check any content in php

Question

I want to see if there are any POST settings. Anyway, can I 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 all the elements are in the array, and you know if there is any set.

echo count($_POST);
