mysql_select_db函数各种失败，加强语句用什么呢
<?php
// header("Content-type:text/html;charset=utf-8");
if($con=mysqli_connect('localhost','xxl','123')){
echo "连接成功";
}else {
echo "连接失败";
}
if(mysql_select_db('info')){
echo '选择成功';
}else{
echo "选择数据库失败";
}
//mysqli_query("set names 'utf-8'");
// mysql_close($con);
?>
