范例
Example #1 获取一个页面并发送 POST 数据
<?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, $context);?>
Example #2 忽略重定向并获取 header 和内容
<?php$url = "http://www.example.org/header.php%22;$opts = array('http' => array( 'method' => 'GET', 'max_redirects' => '0', 'ignore_errors' => '1' ));$context = stream_context_create($opts);$stream = fopen($url, 'r', false, $context);// header information as well as meta data// about the streamvar_dump(stream_get_meta_data($stream));// actual data at $urlvar_dump(stream_get_contents($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 thetcp://
transport. Forhttps://
streams, refer to context options for thessl://
transport.
Note:
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 index0
.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 a200
response (index =4
).
