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？
回复讨论(解决方案)
当然是 echo 啦
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
exit(需要输出的内容)
当然是echo了，如果是json最好加上header标识
<?php$ret = array( 'name' => 'fdipzone');header('content-type:application/json;charset=utf8');echo json_encode($ret);?> echo 或者print_r都行
