我已经使用以下命令开始使用 PHP 5.6 的内置 Web 服务器：

php -S localhost:80

我以前使用过 WAMP 服务器。手册还说，如果您为上述命令提供路由器脚本，请说：

php -S localhost:80 router.php

我们可以实现类似.htaccess. 但我找不到可靠的教程来说明如何进行重定向或包含。现在，我的.htaccess文件有以下内容：

RewriteEngine On
RewriteRule (.*)-(.*)\.htm$ ./?page=$1&sub=$2&%{QUERY_STRING} 
RewriteRule ^([^/]*)\.htm$ ./?page=$1&%{QUERY_STRING} [L]

router.php为了实现与 Apache Web 服务器中相同的输出，我应该放入什么？提前致谢。

老问题，但这是一个简单的版本：

<?php
    /*  Friendly Urls
        ================================================
        RewriteEngine On
        RewriteCond %{SCRIPT_FILENAME} !-f [NC]
        RewriteCond %{SCRIPT_FILENAME} !-d [NC]
        RewriteRule ^(.+)$ /index.php?page=$1 [QSA,L]
        ================================================ */

    $root=__dir__;

    $uri=parse_url($_SERVER['REQUEST_URI'])['path'];
    $page=trim($uri,'/');   

    if (file_exists("$root/$page") && is_file("$root/$page")) {
        return false; // serve the requested resource as-is.
        exit;
    }

    $_GET['page']=$page;
    require_once 'index.php';
?>

通过这种方式，您可以使用您可能已经使用过的法线index.php，例如 Apache 服务器。

我已经包含了一堆“帮助”功能，这将使您更容易编写重写规则（在这里借用）。

我在博客The Reality Tunnel上找到了一个教程，该教程引用了Ripeworks上的一个博客，其中包含一个对我有用的路由器脚本。

他们给出的路由器脚本是

<?php

$root = $_SERVER['DOCUMENT_ROOT'];
chdir($root);
$path = '/'.ltrim(parse_url($_SERVER['REQUEST_URI'])['path'],'/');
set_include_path(get_include_path().':'.__DIR__);
if(file_exists($root.$path))
{
    if(is_dir($root.$path) && substr($path,strlen($path) - 1, 1) !== '/')
        $path = rtrim($path,'/').'/index.php';
    if(strpos($path,'.php') === false) return false;
    else {
        chdir(dirname($root.$path));
        require_once $root.$path;
    }
}else include_once 'index.php';
