POST parameters passed via url empty php

Question

This seems like a very trivial question, but I'm new to php, so please bear with me.

This is the test php script I wrote:

<?php
$str = $_POST['str'];
echo('string entered: '.$str);

I post a request by typing this into the url:

myurl.com/test.php?str=Hello

Now, the response I'm getting is:

string entered:

What am I doing wrong here?
Thanks!

Parameters in URL are GET, so you need to access them like

$param = $_GET['str'];

You're submitting a GET request. To access the parameter, use $_GET['str']

You're passing the variable as a GET parameter, rather than POST. If you want to access the variable this way, you will need to try this:

<?php
$str = $_GET['str'];
echo ('string entered: '.$str);

How would I pass the variable as post parameter?

You will need to pass it with an HTML form, or you can set the value of an existing POST value just like any other array, which is explained here: stackoverflow.com/questions/3418044/….

Alright and I can't do that through the url directly, can I?

Correct. POST is designed to be hidden from the browser, so if you're setting or modifying a value in the parameter list in the URL, you are modifying a GET variable.
