内置Web Server
PHP 5.4.0起， CLI SAPI 提供了一个内置的Web服务器。
这个内置的Web服务器主要用于本地开发使用，不可用于线上产品环境。
URI请求会被发送到PHP所在的的工作目录（Working Directory）进行处理，除非你使用了-t参数来自定义不同的目录。
如果请求未指定执行哪个PHP文件，则默认执行目录内的index.php 或者 index.html。如果这两个文件都不存在，服务器会返回404错误。
当你在命令行启动这个Web Server时，如果指定了一个PHP文件，则这个文件会作为一个“路由”脚本，意味着每次请求都会先执行这个脚本。如果这个脚本返回 FALSE ，那么直接返回请求的文件（例如请求静态文件不作任何处理）。否则会把输出返回到浏览器。
Example #1 启动Web服务器
$ cd ~/public_html $ php -S localhost:8000
终端窗口会显示:
PHP 5.4.0 Development Server started at Thu Jul 21 10:43:28 2011 Listening on localhost:8000 Document root is /home/me/public_html Press Ctrl-C to quit
接着访问http://localhost:8000/和http://localhost:8000/myscript.html，窗口会显示：
PHP 5.4.0 Development Server started at Thu Jul 21 10:43:28 2011 Listening on localhost:8000 Document root is /home/me/public_html Press Ctrl-C to quit. [Thu Jul 21 10:48:48 2011] ::1:39144 GET /favicon.ico - Request read [Thu Jul 21 10:48:50 2011] ::1:39146 GET / - Request read [Thu Jul 21 10:48:50 2011] ::1:39147 GET /favicon.ico - Request read [Thu Jul 21 10:48:52 2011] ::1:39148 GET /myscript.html - Request read [Thu Jul 21 10:48:52 2011] ::1:39149 GET /favicon.ico - Request read
Example #2 启动时指定根目录
$ cd ~/public_html $ php -S localhost:8000 -t foo/
终端窗口显示：
PHP 5.4.0 Development Server started at Thu Jul 21 10:50:26 2011 Listening on localhost:8000 Document root is /home/me/public_html/foo Press Ctrl-C to quit
Example #3 使用路由（Router）脚本
请求图片直接显示图片，请求HTML则显示“Welcome to PHP”
<?php
// router.php
if ( preg_match ( '/\.(?:png|jpg|jpeg|gif)$/' , $_SERVER [ "REQUEST_URI" ]))
return false ; // 直接返回请求的文件
else {
echo "<p>Welcome to PHP</p>" ;
}
?> $ php -S localhost:8000 router.php
执行之后终端显示：
PHP 5.4.0 Development Server started at Thu Jul 21 10:53:19 2011 Listening on localhost:8000 Document root is /home/me/public_html Press Ctrl-C to quit. [Thu Jul 21 10:53:45 2011] ::1:55801 GET /mylogo.jpg - Request read [Thu Jul 21 10:53:52 2011] ::1:55803 GET /abc.html - Request read [Thu Jul 21 10:53:52 2011] ::1:55804 GET /favicon.ico - Request read

Note that to listen on a naked IPv6 address, you have to strangely enclose the address in so-called square brackets. Example:
$ php -S [9990:116:a001:1900::1001]:8080 -t web/

My routing file looks like this:
if (file_exists($_SERVER["DOCUMENT_ROOT"] . $_SERVER["REQUEST_URI"])) {
return false;
} else {
require "index.php";
}
The reason is to support all static files.

If your URI contains a dot, you'll lose the $_SERVER['PATH_INFO'] variable, when using the built-in webserver.
I wanted to write an API, and use .json ending in the URI-s, but then the framework's routing mechanism broke, and it took a lot of time to discover that the reason behind it was its router relying on $_SERVER['PATH_INFO'].

In order to set project specific configuration options, simply add a php.ini file to your project, and then run the built-in server with this flag:
php -S localhost:8000 -c php.ini
This is especially helpful for settings that cannot be set at runtime (ini_set()).

On Windows you may find useful to have a phpserver.bat file in shell:sendto with the folowing:
explorer http://localhost:8888
rem check if arg is file or dir
if exist "%~1\" (
php -S localhost:8888 -t "%~1"
) else (
php -S localhost:8888 -t "%~dp1"
)
then for fast web testing you only have to SendTo a file or folder to this bat and it will open your explorer and run the server.

Just gave it a try, and it is IPv6 compatible, if anyone was wondering.
