$con = mysql_connect('127.0.0.1', 'root', 'root') or die('數(shù)據(jù)庫連接失敗');
if (!$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));
