this [{"uname":"faith"},{"uname":"losh"},{"uname":"loshi"},{"uname":"test"}]
我想把它放到列表视图中,但我不知道该怎么做,而且教程中的方法对我来说不是很清楚。
希望有人可以帮助我...
谢谢你
给出上述结果的php
<?php
include "db_config.php";
$sql=mysql_query("SELECT`uname` FROM `user`");
while($row=mysql_fetch_assoc($sql)) $output[]=$row;
print(json_encode($output));
mysql_close();
?>
活动
这是更正后的,但列表视图仅显示 pwd 列....这是为什么呢?
