I'm looking for an example how to emulate XMLHttpRequest client using PHP.
In other words, send the request over HTTP POST message, and receive and process the callback message.

A:
you can use curl for that purpose
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// set the post
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,array( 'foo' => 'bar'));
// grab URL and pass it to the browser
$result = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
var_dump($result);

A:
The easiest method would be the command line tool curl, especially if you have a sample of the data you want to post.

A:
server.php:
<?php var_dump($_POST);
client.html:
<html>
<head>
<title>omg</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
$(document).ready(function ()
$.post(
"server.php"
, {omg: "wtf"}
, function (data) { alert(data); }
);
);
</script>
</head>
<body></body>
</html>
edit: ok, so it's http client written in PHP!
<?php
$r = new HTTPRequest("server.php", HTTP_METH_POST);
$r->addPostFields(array('omg' => 'wtf'));
$r->send();
var_dump($r->getResponseCode());
var_dump($r->getResponseBody());

I want to implement the client using PHP, not javascript.

Yup nice snippet. Would be better to add a <pre> to the body and then $('pre').append(data); inside the callback function.

An even quicker guide with example to use jQuery.post(): http://docs.jquery.com/Post

A:
If you want to 'really' simulate an AJAX request, you should, together with all of the above solutions, consider sending this header with your request:
X-Requested-With: XMLHttpRequest
(check the manuals to the solutions how to set custom headers). Prototype, jQuery, mootools and the such all send this header when they request data via AJAX.
