HTTP-CONTEXT-OPTIONS(3) 1 HTTP-CONTEXT-OPTIONS(3) HTTP context options - HTTP context option listing Context options for http:// and https:// transports. o $method string - GET, POST, or any other HTTP method supported by the remote server. Defaults to GET. o $header string - Additional headers to be sent during request. Values in this option will override other values (such as User-agent:, Host:, and Authentication:). o $user_agent string - Value to send with User-Agent: header. This value will only be used if user-agent is not specified in the header context option above. By default the user_agent php.ini setting is used. o $content string - Additional data to be sent after the headers. Typically used with POST or PUT requests. o $proxy string - URI specifying address of proxy server. (e.g. tcp://proxy.example.com:5100). o $request_fulluri boolean - When set to TRUE, the entire URI will be used when constructing the request. (i.e. GET http://www.exam- ple.com/path/to/file.html HTTP/1.0). While this is a non-standard request format, some proxy servers require it. Defaults to FALSE. o $follow_location integer - Follow Location header redirects. Set to 0 to disable. Defaults to 1. o $max_redirects integer - The max number of redirects to follow. Value 1 or less means that no redirects are followed. Defaults to 20. o $protocol_version float - HTTP protocol version. Defaults to 1.0. Note PHP prior to 5.3.0 does not implement chunked transfer decoding. If this value is set to 1.1 it is your responsibility to be 1.1 compliant. o $timeout float - Read timeout in seconds, specified by a float (e.g. 10.5). By default the default_socket_timeout php.ini setting is used. o $ignore_errors boolean - Fetch the content even on failure status codes. Defaults to FALSE. +--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.3.4 | | | | | | | Added $follow_location. | | | | | 5.3.0 | | | | | | | The $protocol_version supports chunked transfer | | | decoding when set to 1.1. | | | | |5.2.10 | | | | | | | Added $ignore_errors. | | | | |5.2.10 | | | | | | | The $header can now be an numerically indexed | | | array. | | | | | 5.2.1 | | | | | | | Added $timeout. | | | | | 5.1.0 | | | | | | | Added HTTPS proxying through HTTP proxies. | | | | | 5.1.0 | | | | | | | Added $max_redirects. | | | | | 5.1.0 | | | | | | | Added $protocol_version. | | | | +--------+---------------------------------------------------+ Example #1 Fetch a page and send POST data <?php $postdata = http_build_query( array( 'var1' => 'some content', 'var2' => 'doh' ) ); $opts = array('http' => array( 'method' => 'POST', 'header' => 'Content-type: application/x-www-form-urlencoded', 'content' => $postdata ) ); $context = stream_context_create($opts); $result = file_get_contents('http://example.com/submit.php', false, $context); ?> Example #2 Ignore redirects but fetch headers and content <?php $url = "http://www.example.org/header.php"; $opts = array('http' => array( 'method' => 'GET', 'max_redirects' => '0', 'ignore_errors' => '1' ) ); $context = stream_context_create($opts); $stream = fopen($url, 'r', false, $context); // header information as well as meta data // about the stream var_dump(stream_get_meta_data($stream)); // actual data at $url var_dump(stream_get_contents($stream)); fclose($stream); ?> Note Underlying socket stream context options Additional context options may be supported by the underlying transport For http:// streams, refer to context options for the tcp:// transport. For https:// streams, refer to context options for the ssl:// transport. Note HTTP status line When this stream wrapper follows a redirect, the wrapper_data returned by stream_get_meta_data(3) might not necessarily contain the HTTP status line that actually applies to the content data at index 0. array ( 'wrapper_data' => array ( 0 => 'HTTP/1.0 301 Moved Permantenly', 1 => 'Cache-Control: no-cache', 2 => 'Connection: close', 3 => 'Location: http://example.com/foo.jpg', 4 => 'HTTP/1.1 200 OK', ... The first request returned a 301 (permanent redirect), so the stream wrapper automatically followed the redirect to get a 200 response (index = 4).
