$con = mysql_connect('127.0.0.1', 'root', 'root') or die('數據庫連接失敗');

if (!$con){

?die('Could not connect: ' . mysql_error());

?}

$db_selected = mysql_select_db("test_db",$con);

mysql_query("set names 'utf8'");

$sql = "SELECT * from Person WHERE Lastname='Adams'";

$result = mysql_query($sql,$con);

print_r(mysql_fetch_assoc($result));

報錯如下：
