Introduction
Package Overview
HTTP_Request2 package provides an easy way for PHP applications to perform HTTP requests. It supports a large subset of Hypertext Transfer Protocol features, and can be used for the following:
Working with web services (numerous PEAR packages in Web Services category are using HTTP_Request2 under the hood);
Checking the validity of web links;
Grabbing and parsing remote web pages;
Automated form submission.
Basic Usage Example
Performing a request with HTTP_Request2 consists of the following steps
Creating, configuring and populating an instance of HTTP_Request2 class. At the very least you should set request URL and maybe proxy parameters (if you are using proxy).
Calling send method of that instance. This will pass control to an Adapter that will send the request and read remote server's response. Request's progress may be monitored by using Observers
Processing the returned instance of HTTP_Request2_Response. An instance of HTTP_Request2_Exception can also be thrown by send() if response could not be received (completely or at all) or parsed.

require_once 'HTTP/Request2.php';
$request = new HTTP_Request2('http://pear.php.net/', HTTP_Request2::METHOD_GET);
try {
$response = $request->send();
if (200 == $response->getStatus()) {
echo $response->getBody();
} else {
echo 'Unexpected HTTP status: ' . $response->getStatus() . ' ' .
$response->getReasonPhrase();
}
} catch (HTTP_Request2_Exception $e) {
echo 'Error: ' . $e->getMessage();
}
?>
