整个网站从MySQL检索到的数据库数据中的符号

所以我不知道为什么，但是当我把我的网站从离线突然在线时，网站不会显示任何符号，我不知道为什么。它在线下很好地工作。之前:(整个网站从MySQL检索到的数据库数据中的符号

我的header.php

<?php 
header('Content-Type: text/html; charset=UTF-8'); 
echo <<<_END 

<!DOCTYPE html> 
<html> 
<head> 
    <title>$title</title> 
    <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"> 
    <link href="bootstrap/css/bootstrap.css" rel="stylesheet"> 
    <link href="bootstrap/css/bootstrap-theme.css" rel="stylesheet"> 
    <link href="style.css" rel="stylesheet"> 
</head> 
<body> 
_END;

和index.php文件确实找不到对这个从未见过的任何信息
