PHP接口给C#程序调用返回值以json格式怎么实现？是return还是echo
求解！！！PHP接口给C#程序调用返回值以json格式怎么实现？是return还是echo，到底是用return返回吗？
echo 有用吗？
------解决思路----------------------
当然是 echo 啦
------解决思路----------------------
return只能在php内部使用
对外，你要给别人解析，你就理解成输出，用echo
------解决思路----------------------
当然是echo了，如果是json最好加上header标识

<br /><?php<br />$ret = array(<br />    'name' => 'fdipzone'<br />);<br />header('content-type:application/json;charset=utf8');<br />echo json_encode($ret);<br />?><br />

Copy after login
