PHP给第三方接口POST或GET方式传输数据并得到返回值

function Post($url, $post = null){     $context = array();     if (is_array($post))     {         ksort($post);         $context['http'] = array         (                'timeout'=>60,             'method' => 'POST',             'content' => http_build_query($post, '', '&'),         );     }     return file_get_contents($url, false, stream_context_create($context));}$data = array(     'name' => 'test',     'email' => '[e-mail]',     'submit' => 'submit',);echo Post('http://www.baidu.com', $data);
