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 />
