PHP 8.1.0 RC 2 available for testing

内置Web Server

CLI SAPI 提供了一个内置的Web服务器。


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。

示例 #1 启动Web服务器

$ cd ~/public_html
$ php -S localhost:8000


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


PHP 5.4.0 Development Server started at Thu Jul 21 10:43:28 2011

Document root is /home/me/public_html
Press Ctrl-C to quit.

[Thu Jul 21 10:48:52 2011] ::1:39149 GET /favicon.ico - Request read

示例 #2 启动时指定根目录

$ cd ~/public_html
$ php -S localhost:8000 -t foo/


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

示例 #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”

// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/'$_SERVER["REQUEST_URI"]))
false;    // 直接返回请求的文件
else { 
"<p>Welcome to PHP</p>";
$ php -S localhost:8000 router.php


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

示例 #4 Checking for CLI Web Server Use

To reuse a framework router script during development with the CLI web server and later also with a production web server:

// router.php
if (php_sapi_name() == 'cli-server') {
/* route static assets and return false */
/* go on with normal index.php operations */
$ php -S localhost:8000 router.php

示例 #5 Handling Unsupported File Types

If you need to serve a static resource whose MIME type is not handled by the CLI web server, use:

// router.php
$path pathinfo($_SERVER["SCRIPT_FILENAME"]);
if (
$path["extension"] == "el") {
header("Content-Type: text/x-script.elisp");
else {
$ php -S localhost:8000 router.php

示例 #6 Accessing the CLI Web Server From Remote Machines

You can make the web server accessible on port 8000 to any interface with:

$ php -S

The built-in Web Server should not be used on a public network.

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()).

It’s not mentioned directly, and may not be obvious, but you can also use this to create a virtual host. This, of course, requires the help of your hosts file.

Here are the steps:

1    /etc/hosts

2    cd [root folder]
    php -S

3    Browser:

Combined with a simple SQLite database, you have a very handy testing environment.

I painfully experienced behaviour that I can't seem to find documented here so I wanted to save everyone from repeating my mistake by giving the following heads up:

When starting php -S on a mac (in my case macOS Sierra) to host a local server, I had trouble with connecting from legacy Java.

As it turned out, if you started the php server with
"php -S localhost:80"
the server will be started with ipv6 support only!

To access it via ipv4, you need to change the start up command like so:
"php -S"
which starts server in ipv4 mode only.

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'].

To send environment variable as long as with PHP built-in web server, type like this.

~$ MYENV=dev php -d variables_order=EGPCS -S

On PHP script we can check with this code.

echo getenv('MYENV'); // print dev

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.

To output debugging information on the command line you can write output to php://stdout:


file_put_contents("php://stdout", "\nRequested: $path");
"<p>Hello World</p>";

Listen on all addresses of IPv4:
php -S

Listen on all addresses of IPv6:
php -S [::0]:80

If you have trouble with a project using both dynamic routes containing dots (giving unexpected 404 errors) and static file hosting paste this in your index.php

// Support cli server for local development
if (php_sapi_name() === 'cli-server') {
    $fileName = __DIR__.parse_url($_SERVER["REQUEST_URI"], PHP_URL_PATH);
    if (file_exists($fileName) && !is_dir($fileName)) return false;

Then run the internal server directly on the file:

php -S index.php

I fiddled around with the internal webserver and had issues regarding handling static files, that do not contain a dot and a file extension.

The webserver responded with 200 without any content for files with URIs like "/testfile".

I am not certain if this is a bug, but I created a router.php that now does not use the "return false;" operation in order to pass thru the static file by the internal webserver.

Instead I use fpassthru() to do that.

In addition to that, my router.php can be configured to...
- ... have certain index files, when requesting a directory
- ... configure regex routes, so that, if the REQUEST_URI matches the regex, a certain file or directory is requested instead. (something you would do with nginx config or .htaccess ModRewrite)

Maybe someone finds this helpful.



= ['index.html', 'index.php'];
$routes = [
'^/api(/.*)?$' => '/index.php'

$requestedAbsoluteFile = dirname(__FILE__) . $_SERVER['REQUEST_URI'];

// check if the the request matches one of the defined routes
foreach ($routes as $regex => $fn)
  if (
preg_match('%'.$regex.'%', $_SERVER['REQUEST_URI']))
$requestedAbsoluteFile = dirname(__FILE__) . $fn;

// if request is a directory call check if index files exist
if (is_dir($requestedAbsoluteFile))
  foreach (
$indexFiles as $filename)
$fn = $requestedAbsoluteFile.'/'.$filename;
    if (
$requestedAbsoluteFile = $fn;

// if requested file does not exist or is directory => 404
if (!is_file($requestedAbsoluteFile))
header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found');
printf('"%s" does not exist', $_SERVER['REQUEST_URI']);

// if requested file is'nt a php file
if (!preg_match('/\.php$/', $requestedAbsoluteFile)) {
header('Content-Type: '.mime_content_type($requestedAbsoluteFile));
$fh = fopen($requestedAbsoluteFile, 'r');

// if requested file is php, include it
include_once $requestedAbsoluteFile;

Just a note to people who also use windows 8.1, or anyone who has had this problem when running the using the PHP server CLI.

`PHP -S localhost:8000 -t /public` <-- Not going to work.

`PHP -S localhost:8000 -t public` <-- Works!

And there is something else up in the notes saying something about you can't serve a project folder and a router file. Well, actually you can! At least for me.

`PHP -S localhost:8000 router.php -t public` <-- Perhaps someone tries this and it doesn't work.

`PHP -S localhost:8000 -t public router.php` <-- Works!

For serving static content like .css or .js and otherwise using a router (for me it was index.php)  this worked out of the box for me:

   php -S localhost:8000

Due to my router file was index.php. But

   php -S localhost:8000 index.php

did not work, because my static files are not served via my router.

$_SERVER['SERVER_ADDR'] is not defined when using php as the built-in commandline web server, so you can not use $_SERVER['SERVER_ADDR'] to detect the Server's IP address.

P.S.: This is tested on Windows with PHP 7.1 on 2016-12-22.

You can also print messages to the server's STDOUT via error_log().

Also the documentation doesn't make it clear that when you use router script if a PHP file is requested and you return false, the PHP file will be served (i.e. you do not need to load and eval it manually).

Note: The built-in web server has a file size limit. For files larger than 5 GB, it will always serve a "File not found" error page.
