Notes:
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.
HTTP status line
When this stream wrapper follows a redirect, the wrapper_data returned by stream_get_meta_data() 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).
Examples:
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); ?>
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); ?>
