Question

所以我不知道为什么，但是当我从离线网站上网时突然网站不会显示任何符号，我不知道为什么。它离线工作得很好。真的无法找到以前从未见过的任何信息:(

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

<?php
$title = 'Baz Building';
require_once 'header.php';
require_once 'nav.php';
?>
<div class="container">
    <h1>Welcome to baz Build by Richard Hayward</h1><br><br>

        //Get connection details from file
        require_once'mysqli-con.php';
        //Create new connection
        $conn = new mysqli($hn, $un, $pw, $db); //Create new object, MYSQLI connection
        if ($conn->connect_error) die ($conn->connect_error); //Display error if failed to connect


         // Create first query to get all house names for count

        for($c = 0 ; $c < $num_rows ; ++$c){

            //Query Join
            $query_names->data_seek($c);
        $name = $query_names->fetch_array(MYSQLI_NUM);

            $query = "SELECT house_names.id, house_names.name, houses_has_features.house_names_id, house_types.type, features.feature FROM house_names

Answer 1

这篇关于unicode的文章值得一读：The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets

关于编码的最重要事实

如果你完全忘记我刚才解释的一切，请记住   一个非常重要的事实。拥有一个字符串是没有意义的   不知道它使用什么编码。你再也不能坚持了   在沙滩上，假装“普通”文字是ASCII。

没有像纯文本那样的东西。

Answer 2

检查相对路径，URL是WWW ot，没有www
