Introduction to HTTP_Request
Overview
With this package, one can easily perform HTTP request from within PHP scripts. It support GET/POST/HEAD/TRACE/PUT/DELETE, Basic authentication, Proxy, Proxy Authentication, SSL, file uploads etc.
Because of the above mentioned features HTTP_Request makes it possible to mimic big parts of web browsers such as the widely-known Mozilla browser in PHP applications. Possible application areas are:
- Checking the validity of WWW links with the help of getResponseCode.
- Grabbing remote web pages and parsing the result.
- etc.
A few examples
Fetches yahoo.com and displays it
<?php
require_once "HTTP/Request.php";
$req =& new HTTP_Request("http://www.yahoo.com/");
if (!PEAR::isError($req->sendRequest())) {
echo $req->getResponseBody();
}
?>
Fetching two website in a row
In this example, two websites are fetched and displayed. To the first one a POST parameter is passed. The POST data stack is cleared before the second website is fetched.
<?php
require_once "HTTP/Request.php";
$req =& new HTTP_Request("http://www.php.net");
$req->setMethod(HTTP_REQUEST_METHOD_POST);
$req->addPostData("Foo", "bar");
if (!PEAR::isError($req->sendRequest())) {
$response1 = $req->getResponseBody();
} else {
$response1 = "";
}
$req->setMethod(HTTP_REQUEST_METHOD_GET);
$req->setURL("http://pear.php.net");
$req->clearPostData();
if (!PEAR::isError($req->sendRequest())) {
$response2 = $req->getResponseBody();
} else {
$response2 = "";
}
echo $response1;
echo $response2;
?>
