php做服务端接受数据问题

本帖最后由 chaoyangqq 于 2014-03-22 08:40:28 编辑 底层不太懂队友做的只能发送http报文data中的数据是要读取的,我应该怎么与他进行通信啊!我尝试用curl读取可是不成功
curl_setopt($ch, CURLOPT_URL,"192.168.16.254:8080");<br />        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);<br />        //要求保存到字符串还是输出到屏幕上,1隐藏<br />        curl_setopt($ch, CURLOPT_TIMEOUT, 1);//最多获取一秒的信息<br />        curl_setopt($ch, CURLOPT_HEADER, 0);<br />        echo $output = curl_exec($ch);<br />        curl_close($ch);

求指导。
------解决方案--------------------
经过我查找的资料 php做的服务器接受客户端的数据可以通过$_POST,$_GET,$_REQUEST来获取。 客户端需要用对应的$_post,$_get 来提交数据,$_REQUEST似乎都可以。
至于$_POST,$_GET的区别,百度上太多了 你可以自己找找
$_POST,$_GET返回的就是你客户端传过来的参数,你可以通过处理这些参数来完成功能,至于你想返回数据给客户端,只需要echo就行了 
我最近做的php服务器,不知道是什么原因,用$_POST,$_GET,$_REQUEST不能获取到数据。 所以找了$GLOBALS[$HTTP_RAW_POST_DATA]和file_get_contents("http://input")来获取数据
上面两个方式都能获取客户端post过来的请求 第一个听说似乎不能收一种数据,忘了  
我使用的是第二个 $request = file_get_contents("http://input") 就得到了客户端post过来的参数了

我只是工作需要才临时做下php服务器的,没经过系统学习,所以懂得不多。刚好我刚弄好了php服务器。 希望对你有帮助。

echo $output = curl_exec($ch); 没有数据吗?

出现可能的原因
1.192.168.16.254:8080 这个页面没有输出。
2.curl连接错误,可以加curl_error查看错误。
<br />if(curl_errno($ch)){<br />echo 'curl error:'.curl_error($ch);<br />}<br />
