Manuale PHP | http://https://http:// -- https:// — Accessing HTTP(s) URLs DescriptionAllows read-only access to files/resources via HTTP 1.0, using the HTTP GET method. A Host: header is sent with the request to handle name-based virtual hosts. If you have configured a user_agent string using your php.ini 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. The from directive will be used for the From: header if set and not overwritten by the Context options and parameters. Options

ExamplesExample #1 Detecting which URL we ended up on after redirects
<?php Example #2 Sending custom headers with an HTTP request Custom headers may be sent with an HTTP request by taking advantage of a side-effect in the handling of the user_agent INI setting. Set user_agent to any valid string (such as the default PHP/version setting) followed by a carriage-return/line-feed pair and any additional headers. This method works in PHP 4 and all later versions.
<?php Results in the following request being sent: GET /index.php HTTP/1.0 Host: www.example.com User-Agent: PHP X-MyCustomHeader: Foo Notes
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. See Also
