动态更改标题和描述

Question

我想从需要 MySQL 查询的页面生成动态标题和描述：

index.php

<html>
<head>
    <?php
    switch($page):
        case 'home':
            $body   = 'home.php';
            $title    = 'Home';  
        break;
    
        case 'contact':
            $body   = 'contact.php';
            $title    = 'Contact';  
        break;
    
        case 'members':
            $body   = 'members.php';
            $title    = 'I should put here the member profile';  
        break;
        
    /*
     * More pages
     */
        
        
    endswitch;

    ?>

    <title><?php echo $title; ?></title>
</head>

<body>
    <?php
        require_once $body;
    ?>
    
</body>

那么比如我应该调用页面，例如：

members.php 页

<?php
$sql = "SELECT * FROM members WHERE mem_id = :mem_id";
/*
 * More codes
 */

foreach($res as $f):
    $mem_name       = $f['mem_name'];
endforeach;

$newTitle   = 'Profile of '.$meme_name;

 ?>

那么我怎样才能把从MySQL查询生成的$newTitle放在标题标签

正如我们从给定的代码中看到的，您可以在下面执行此操作。如果您真的不想重写整个代码。

members.php

<?php
$sql = "SELECT * FROM members WHERE mem_id = :mem_id";
/*
 * More codes
 */

foreach($res as $f):
    $mem_name       = $f['mem_name'];
endforeach;

$newTitle   = 'Profile of '.$meme_name;

require_once $body;
 ?>

// put this at the buttom of your body
<script>
document.title="<?php echo $newTitle;?>"
</script>

不过还是建议大家一开始就准备好服务器端的变量，这样就不会遇到这种问题了。
