how to get string from xmlhttp.send(str) via POST in PHP

My code looks like that: Client side JavaScript:

xmlhttp=new XMLHttpRequest();
xmlhttp.open("POST",url + page,true);
xmlhttp.send(str);

I'm missing the code to in PHP side to extract this string, which I assume is in the http post body.

Is it possible to send string array or is this method is restricted for xmls and strings?

As Canttouchit said, these headers must be send for any POST request:

xhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded"); // for POST escaped 'form' data
xhttp.setRequestHeader("Content-length", post_str.length);
xhttp.setRequestHeader("Connection", "close");

You can send any data you like.

Usually, you would encode the data as application/x-www-form-urlencoded:

var data = "foo=" + encodeURIComponent(data) + "&bar=" + encodeURIComponent(more_data);
xmlhttp.send(data);

And then access it via $_POST['foo'] and $_POST['bar'].

If you want to access the raw data, then you can access it via file_get_contents('php://input');

Use setRequestHeader to specify the content type of the data you are sending.
