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' => '[email protected]',
     'submit' => 'submit',
);

echo Post('http://www.baidu.com', $data);
