<?php
$hostName = "localhost";
$usrName = "root";
$passWord = "root";
$port = "3306";
$dbname = "flyingman";
$content = mysqli_connect($hostName,$usrName,$passWord,$dbname,$port);
mysqli_set_charset($content,'utf-8');
if(!$content){
    die("connect failed!：".mysqli_connect_error());
}else{
    echo "connect success!";
}
mysqli_close($content);

header("content-type:text/html;charset=utf-8");
