A stream context resource.

Example

A runnable snippet:

$default_opts = [ 'http' => [ 'method' => "GET", 'header' => "Accept-language: en\r\n" . "Cookie: foo=bar", 'proxy' => "tcp://10.54.1.39:8000", ] ]; $alternate_opts = [ 'http' => [ 'method' => "POST", 'header' => "Content-type: application/x-www-form-urlencoded\r\n" . "Content-length: " . strlen("baz=bomb"), 'content' => "baz=bomb", ] ]; $default = stream_context_get_default($default_opts); $alternate = stream_context_create($alternate_opts); /* Sends a regular GET request to proxy server at 10.54.1.39 * For www.example.com using context options specified in $default_opts */ readfile('http://www.example.com'); /* Sends a POST request directly to www.example.com * Using context options specified in $alternate_opts */ readfile('http://www.example.com', false, $alternate);
