Servidor web embutido

Aviso

Esse servidor web foi desenvolvido para auxiliar no desenvolvimento de aplicações. Ele também pode ser útil para testes ou para demonstrações de aplicações que forem executadas em ambientes controlados. Ele não foi desenvolvido para ser um web server completo. Ele não deve ser utilizado em uma rede pública.

O CLI SAPI fornece um servidor web embutido.

Esse servidor embutido roda apenas um processo single-thread, de forma que aplicações PHP irão congelar se uma requisição bloquear.

Requisições de URI são servidas a partir do diretório atual onde o PHP foi iniciado, a não ser que a opção -t seja usada para especificar uma raiz de documento explicitamente. Se uma requisição de URI especificar um arquivo específico então ou o index.php ou index.html no diretório em questão será retornado. Se nenhum deles existir, a procura por index.php e index.html continuará nos diretórios superiores até que algum deles seja encontrado ou o document root seja alcançado. Caso um index.php ou index.html seja encontrado então é retornado e $_SERVER['PATH_INFO'] é configurado para a parte final da URI. Caso contrário uma resposta 404 é retornada.

Se um arquivo PHP for fornecido na linha de comando quando o servidor web for iniciado ele será tratado como roteador. O script é executado no inicio de cada requisição HTTP. Se o script retornar false, então o recurso requisitado será retornado da maneira como estiver. Do contrário, a saída do script será retornada para o navegador.

MIME types padrões serão retornados para arquivos com as extensões: .3gp, .apk, .avi, .bmp, .css, .csv, .doc, .docx, .flac, .gif, .gz, .gzip, .htm, .html, .ics, .jpe, .jpeg, .jpg, .js, .kml, .kmz, .m4a, .mov, .mp3, .mp4, .mpeg, .mpg, .odp, .ods, .odt, .oga, .ogg, .ogv, .pdf, .pdf, .png, .pps, .pptx, .qt, .svg, .swf, .tar, .text, .tif, .txt, .wav, .webm, .wmv, .xls, .xlsx, .xml, .xsl, .xsd, and .zip.

Changelog
Versão Descrição
7.4.0 Você pode configurar o servidor web embutido para trabalhar com várias threads em paralelo para testar código que requeira requisições concorrentes ao servidor. Configure a variável de ambiente PHP_CLI_SERVER_WORKERS para o número de workers desejados antes de iniciar o servidor. Essa opção não é suportada no Windows.
Aviso

Esse recurso é experimental e não é desenhado para uso em produção. O servidor web embutido não é desenhado para uso em produção.

Exemplo #1 Iniciando o servidor web

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

O terminal irá exibir:

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

Após serem feitas requisições de URI para for http://localhost:8000/ e http://localhost:8000/myscript.html o terminal irá exibir algo similar a:

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

Note que antes do PHP 7.4.0, recursos estáticos representados por symlinks não eram acessíveis pelo Windows, sendo necessário um script de roteamento nesses casos.

Exemplo #2 Iniciando o servidor web com um diretório raiz específico

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

O terminal irá exibir:

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

Exemplo #3 Usando um script de roteamento

Nesse exemplo, requisições para imagens serão exibidas, mas requisições para arquivos HTML irão exibir "Welcome to PHP":

<?php
// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"])) {
return
false; // serve the requested resource as-is.
} else {
echo
"<p>Welcome to PHP</p>";
}
?>
$ php -S localhost:8000 router.php

Exemplo #4 Verificando o Uso do CLI Web Server

Para reutilizar um script de roteamento específico de um framework durante o desenvolvimento com o servidor web CLI e depois também em um servidor de produção:

<?php
// 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

Exemplo #5 Tratando de tipos de arquivos não suportados

Se você precisar servir um recurso estático cujo MIME type não é tratado pelo servidor web CLI, use:

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

Exemplo #6 Acessando o servidor web CLI de máquinas remotas

Você pode tornar o servidor web acessível na porta 8000 para qualquer interface com:

$ php -S 0.0.0.0:8000
Aviso

O servidor web embutido não deve ser exposto em redes públicas.

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
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.

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.

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'].

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:

<?php
$path
= $_SERVER["SCRIPT_FILENAME"];

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

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

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

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;

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.

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).

$_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.

Below is the printed $_SERVER variable.

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

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.
