定义:Stream Contexts
A context is a set of parameters and wrapper specific options which modify or enhance the behavior of a stream. Contexts are created using stream_context_create() and can be passed to most filesystem related stream creation functions (i.e. fopen(), file(), file_get_contents(), etc…).
常用法
resource stream_context_create ([ array $options [, array $params ]] )
array(
'method'=>"GET",
'header'=>"Accept-language: en\r\n" .
"Cookie: foo=bar\r\n"
)
);
$context = stream_context_create($opts);
$fp = fopen('http://www.example.com', 'r', false, $context);
fpassthru($fp);
fclose($fp);
