Встроенный web-сервер
Начиная с версии PHP 5.4.0 модуль CLI SAPI содержит встроенный web-сервер.
Этот web-сервер предназначен для использования при разработке и не должен использоваться на обычном сервере.
Запросы обслуживаются последовательно.
URI запросы обслуживаются из текущей директории, в которой был запущен PHP, если не используется опция -t для явного указания корневого документа. Если URI запроса не указывает на определенный файл, то будет возвращен либо index.php либо index.html в указанной директории. Если оба файла отсутствуют, то возвращается 404 код ответа.
Если PHP-файл указывается в командной строке, когда запускается веб-сервер,
то он рассматривается как скрипт "маршрутизации". Скрипт выполняется
в самом начале после каждого HTTP-запроса. Если этот скрипт возвращает
FALSE, то запрашиваемый ресурс возвращается как есть.
В противном случае браузеру будет возвращен вывод этого скрипта.
Стандартные MIME-типы возращаются для файлов со следующими расширениями: .css, .gif, .htm, .html, .jpe, .jpeg, .jpg, .js, .png, .svg, и .txt. Расширения .htm и .svg определяются начиная с PHP 5.4.4.
Пример #1 Запуск web-сервера
$ cd ~/public_html $ php -S localhost:8000
В консоли выведется:
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
После URI запросов http://localhost:8000/ и http://localhost:8000/myscript.html в консоли выведется примерно следующее:
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
Пример #2 Запуск с указанием корневой директории
$ cd ~/public_html $ php -S localhost:8000 -t foo/
В консоли выведется:
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
Пример #3 Использование скрипта маршрутизации
В этом примере, запросы изображений будут возвращать их, но запросы HTML файлов будут возвращать "Welcome to PHP".
<?php
// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"])) {
return false; // сервер возвращает файлы напрямую.
} else {
echo "<p>Welcome to PHP</p>";
}
?>
$ php -S localhost:8000 router.php
Пример #4 Проверка использования CLI web-сервера
Для совместного использования скрипта маршрутизации при разработке с CLI web-сервером и в дальнейшем с боевым web-сервером:
<?php
// router.php
if (php_sapi_name() == 'cli-server') {
/* Маршрутизация с заданными правилами и выход с возвращением false */
}
/* продолжение с обычными операциями index.php */
?>
$ php -S localhost:8000 router.php
Пример #5 Поддержка неподдерживаемых типов файлов
Если вам нужно обслуживать статические ресурсы с MIME типами неподдерживаемыми CLI web-сервером:
<?php
// router.php
$path = pathinfo($_SERVER["SCRIPT_FILENAME"]);
if ($path["extension"] == "ogg") {
header("Content-Type: video/ogg");
readfile($_SERVER["SCRIPT_FILENAME"]);
}
else {
return FALSE;
}
?>
$ php -S localhost:8000 router.php
Пример #6 Доступ к CLI web-серверу с удаленных машин
Вы можете сделать web-сервер доступным на 8000 порту для всех сетевых интерфейсов:
$ php -S 0.0.0.0:8000
Коментарии
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.
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()).
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'].

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
127.0.0.1 www.example.com
2 cd [root folder]
php -S www.example.com:8000
3 Browser:
http://www.example.com:8000/index.php
Combined with a simple SQLite database, you have a very handy testing environment.
To output debugging information on the command line you can write output to php://stdout:
<?php
$path = $_SERVER["SCRIPT_FILENAME"];
file_put_contents("php://stdout", "\nRequested: $path");
echo "<p>Hello World</p>";
?>
$_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.

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 127.0.0.1:80"
which starts server in ipv4 mode only.
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.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).
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!
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.
================================
<?php
$indexFiles = ['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__) . $fn;
break;
}
}
// if request is a directory call check if index files exist
if (is_dir($requestedAbsoluteFile))
{
foreach ($indexFiles as $filename)
{
$fn = $requestedAbsoluteFile.'/'.$filename;
if (is_file($fn))
{
$requestedAbsoluteFile = $fn;
break;
}
}
}
// if requested file does not exist or is directory => 404
if (!is_file($requestedAbsoluteFile))
{
header($_SERVER['SERVER_PROTOCOL'].' 404 Not Found');
printf('"%s" does not exist', $_SERVER['REQUEST_URI']);
return true;
}
// if requested file is'nt a php file
if (!preg_match('/\.php$/', $requestedAbsoluteFile)) {
header('Content-Type: '.mime_content_type($requestedAbsoluteFile));
$fh = fopen($requestedAbsoluteFile, 'r');
fpassthru($fh);
fclose($fh);
return true;
}
// if requested file is php, include it
include_once $requestedAbsoluteFile;
For serving static content like .css or .js and otherwise using a router (for me it was index.php) this worked out of the box for me:
php -S localhost:8000
Due to my router file was index.php. But
php -S localhost:8000 index.php
did not work, because my static files are not served via my router.
To send environment variable as long as with PHP built-in web server, type like this.
~$ MYENV=dev php -d variables_order=EGPCS -S 0.0.0.0:8000
On PHP script we can check with this code.
<?php
echo getenv('MYENV'); // print dev
Listen on all addresses of IPv4:
php -S 0.0.0.0:80
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 127.0.0.1 index.php
Built-in web server uses SAPI logging subsystem. Therefore all messages are written to standard error, and not to standard output stream.If you want to save server logs into a file, the following command will work:
php -S 0.0.0.0:80 2>&1 | tee out.log
