更改標題動態創建的PHP頁面

Question

我有使用產生的其它頁面只有一個index.php文件：

RewriteRule ^page 1.php$ index.php?cat=a [NC] 
RewriteRule ^page 2.php$ index.php?cat=b [NC] 

我嘗試使用下面的代碼來改變我的網頁的標題，但它只爲index.php工作。

<?php 
$page = $_SERVER['PHP_SELF']; 
if(isset($page)) { 
switch($page) { 
case "/index.php": 
$title = "this is homepage"; 
break; 
case "/page 1.php": 
$title = "products"; 
break; 
case "/page 2.php": 
$title = "services"; 
break; 
} 
}else{ 
$title = "default title"; 
} 

print "<title>$title</title>"; 
?> 

Answer 1

驗證的空間我不知道他們允許的URL

，看一下文檔：

http://php.net/manual/en/reserved.variables.server.php

試試這個：

<?php 
$page = $_GET['cat']; 
if(isset($page)) { 
switch($page) { 
case "index": 
$title = "this is homepage"; 
break; 
case "a": 
$title = "products"; 
break; 
case "b": 
$title = "services"; 
break; 
} 
}else{ 
$title = "default title"; 
} 

print "<title>$title</title>"; 
?> 

Answer 2

使用在你重寫規則而不是空間：

RewriteRule ^page\s1.php$ index.php?cat=a [NC] 
RewriteRule ^page\s2.php$ index.php?cat=b [NC]
