Accessing HTTP(s) URLs
ENTITY
Allows read-only access to files/resources via HTTP. By default, a HTTP 1.0 GET is used. A Host: header is sent with the request to handle name-based virtual hosts. If you have configured a user_agent string using your ENTITY file or the stream context, it will also be included in the request.
The stream allows access to the body of the resource; the headers are stored in the $http_response_header variable.
If it's important to know the URL of the resource where your document came from (after all redirects have been processed), you'll need to process the series of response headers returned by the stream.

ENTITY
Detecting which URL we ended up on after redirects
<?php
$url = 'http://www.example.com/redirecting_page.php';
$fp = fopen($url, 'r');
$meta_data = stream_get_meta_data($fp);
foreach ($meta_data['wrapper_data'] as $response) {
/* Were we redirected? */
if (strtolower(substr($response, 0, 10)) == 'location: ') {
/* update $url with where we were redirected to */
$url = substr($response, 10);
}
}
?>
ENTITY
[!NOTE] HTTPS is only supported when the openssl extension is enabled.
HTTP connections are read-only; writing data or copying files to an HTTP resource is not supported.
Sending POST and PUT requests, for example, can be done with the help of HTTP Contexts.
