Android通过PHP连接MySQL：

insert.php

<php
mysql_connect("127.0.0.1","root","123456");
mysql_query("SET NAMES utf8");
mysql_select_db("test");

$sql=mysql_query("insert into teacher (id,name) values('$_POST[id]','$_POST[name]')");
while($row=mysql_fetch_assoc($sql))
$output[]=$row;
print(json_encode($output));
mysql_close();
