file_get_contents版本：
1 /** 2 * 发送post请求 3 * @param string $url 请求地址 4 * @param array $post_data post键值对数据 5 * @return string 6 */ 7 function send_post($url, $post_data) { 8 9 $postdata = http_build_query($post_data);10 $options = array(11 'http' =>; array(12 'method' =>; 'post',13 'header' =>; 'content-type:application/x-www-form-urlencoded',14 'content' =>; $postdata,15 'timeout' =>; 15 * 60 // 超时时间（单位:s）16 )17 );18 $context = stream_context_create($options);19 $result = file_get_contents($url, false, $context);20 21 return $result;22 }
使用如下：
1 post_data = array(2 'username' => 'stclair2201',3 'password' => 'handan'4 );5 send_post('http://blog.snsgou.com', $post_data);
实战经验：
当我利用上述代码给另一台服务器发送http请求时，发现，如果服务器处理请求时间过长，本地的php会中断请求，即所谓的超时中断，第一个怀疑的是php本身执行时间的超过限制，但想想也不应该，因为老早就按照这篇文章设置了“php执行时间限制”（【推荐】php上传文件大小限制大全 ），仔细琢磨，想想，应该是http请求本身的一个时间限制，于是乎，就想到了怎么给http请求时间限制搞大一点。。。。。。查看php手册，果真有个参数 “ timeout ”，默认不知道多大，当把它的值设大一点，问题得已解决，弱弱地做个笔记~~~

调用 wcf接口 的一个例子：$json = restrequest($r_url,'post', json_encode($data));
