How do I send POST requests with AJAX ?

Hi.

I'm trying to send some data (strings, arrays…) to my PHP file.

When I'm using "AJAX -> request URL" with GET data it works perfectly, but I don't understand how I should use "AJAX -> post to URL" : it always returns an empty array if I do a "print_r($_POST);" in my PHP file.

How I should use this if I want to send for example an array content ?

data must be formatted like this: "variable="&variable

your php file:

$var = $_POST["variable"]

Great, thanks.
