Servidor web interno


Este servidor web ha sido diseñado para ayudar al desarrollo de aplicaciones. También puede ser útil para propósitos de prueba o para demostraciones de aplicaciones que se ejecutan en entornos controlados. No se pretende que sea un servidor web con todas las funciones. No debe ser utilizado en una red pública.

Desde PHP 5.4.0, la SAPI CLI provee un servidor web embebido.

El servidor web ejecuta solamente un único proceso monohilo, por lo que las aplicaciones PHP se detendrán si la solicitud está bloqueada.

Las peticiones de URI se sirven desde el actual directorio de trabajo donde PHP se inició, a menos que la opción -t sea utilizada para especificar una raíz de documentos explícita. Si una petición de URI no especifica un fichero, entonces el index.php o index.html que estén en el directorio dado serán devueltos. Si ninguno de los ficheros existen, la búsqueda de index.php e index.html continuará en el directorio padre y continuará así hasta encontrar uno de ello o se alcance el directorio raíz. Si se encuentra index.php o index.html, se devuelve este y $_SERVER['PATH_INFO'] se establece a la parte final del URI. De lo contrario se devuelve un código de respuesta 404.

Si un fichero PHP es proporcionado en la línea de comandos cuando se inicia el servidor web éste es tratado como un script "enrutador". El script es ejecutado al inicio de cada petición HTTP. Si este script devuelve false, entonces el recurso solicitado se devuelve tal cual está. De otra forma la salida del script se devuelve en el navegador.

Los tipos MIME estándar son devueltos para ficheros con extensiones: .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, y .zip.

Ejemplo #1 Iniciando el servidor web

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

La terminal mostrará:

PHP 5.4.0 Servidor de desarrollo iniciado en Jueves Julio 21 10:43:28 2011
Escuchando en localhost:8000
La raíz de documentos es /home/usuario/html_público
Presione Ctrl-C para salir

Después de una petición de una URI para http://localhost:8000/ y http://localhost:8000/mi_script.html la terminal mostrará algo similar a:

PHP 5.4.0 Servidor de desarrollo iniciado en Jueves Julio 21 10:43:28 2011
Escuchando en localhost:8000
La raíz de documentos es /home/usuario/html_público
Presione Ctrl-C para salir.
[Thu Jul 21 10:48:48 2011] ::1:39144 GET /favicon.ico - Petición leída
[Thu Jul 21 10:48:50 2011] ::1:39146 GET / - Petición leída
[Thu Jul 21 10:48:50 2011] ::1:39147 GET /favicon.ico - Petición leída
[Thu Jul 21 10:48:52 2011] ::1:39148 GET /mi_script.html - Petición leída
[Thu Jul 21 10:48:52 2011] ::1:39149 GET /favicon.ico - Petición leída

Ejemplo #2 Iniciando con una raíz de documentos específica

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

La terminal mostrará:

PHP 5.4.0 Servidor de desarrollo iniciado en Jueves Julio 21 10:50:26 2011
Escuchando en localhost:8000
La raíz de documentos es /home/usuario/html_público/foo
Presione Ctrl-C para salir

Ejemplo #3 Utilizando un Script enrutador

En este ejemplo, las peticiones a las imágenes se mostrarán, pero las peticiones a ficheros HTML mostrarán "Bienvenido a PHP":

// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"])){
false; // servir la petición tal cual es.
}else {
"<p>Bienvenido a PHP</p>";

$ php -S localhost:8000 router.php

Ejemplo #4 Revisión del uso de la CLI del servidor web

Para reutilizar un framework de script enrutador durante el desarrollo con la CLI del servidor web server y luego con un servidor web en producción:

// router.php
if (php_sapi_name() == 'cli-server') {
/* los activos de ruta estática y devolver falso */
/* seguir adelante con operaciones normales de index.php */
$ php -S localhost:8000 router.php

Ejemplo #5 Manejando tipos de ficheros no soportados

Si necesita servir un recurso estático cuyo tipo MIME no es manejado por la CLI del servidor web, utilice:

// 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

Ejemplo #6 Accediendo a la CLI del servidor web desde máquinas remotas

Puede hacer que el servidor web sea accesible en el puerto 8000 a cualquier interfaz con:

$ php -S

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'].

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

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 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

On PHP script we can check with this code.

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.



= ['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.

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 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.
