Web server interno


Questo server web è stato sviluppato per aiutare lo sviluppo di applicazioni. Può anche essere utile per scopo di test o per dimostrazioni applicative che sono eseguite in ambienti controllati. Non è destinato ad essere un web server con tutte le funzionalità. Non dovrebbe essere usato su una rete pubblica.

La CLI SAPI fornisce un web server interno.

Il web server esegue solo un processo con un thread, quindi le applicazioni PHP andranno in stallo se una richiesta è bloccata.

Le richieste URI sono eseguite dalla cartella di lavoro corrente, in cui PHP è stato eseguito, a meno che non sia stata usata l'opzione -t per specificare una radice dei documenti. Se una richiesta URI non specifica un file, allora viene restituito o index.php o index.html nella directory data. Se i file non esistono, la ricerca per index.php e index.html continuerà nella cartella padre e così via finchè non ne viene trovato uno o non viene raggiunto il document root. Se viene trovato un index.php o un index.html, esso viene restituito e viene impostato $_SERVER['PATH_INFO'] alla parte finale dell'URI. In caso contrario viene restituita una risposta con il codice 404.

Se un file PHP viene specificato sulla linea di comando quando viene attivato il web server, viene trattato come script "router" per il web server. Lo script è eseguito all'inizio di ogni richiesta HTTP. Se restituisce false, la risorsa richiesta viene ritornata così com'è. altrimenti viene restituito al browser il risultato dello script.

I tipi MIME standard vengono restituiti per i file con le estensioni: 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, e .zip.

Versione Descrizione
7.4.0 Si può configurare il server web integrato per eseguire il fork di più worker per testare il codice che richiede più richieste simultanee al server web integrato. Impostare la variabile di ambiente PHP_CLI_SERVER_WORKERS al numero di worker desiderati prima di avviare il server. Questo non è supportato su Windows.

Questa funzione sperimentale non è destinata all'uso in produzione. In genere, il server Web integrato non è destinato all'uso in produzione.

Example #1 Avvio del web server

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

Il terminale mostrerà:

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

Dopo le richiste URI per http://localhost:8000/ e http://localhost:8000/myscript.html il terminale mostrerà qualcosa di simile 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

Notare che prima di PHP 7.4.0, le risorse statiche con collegamenti simbolici non erano accessibili su Windows, a meno che lo script del router non le gestisse.

Example #2 Esecuzione con una cartella di radice dei documenti specifica

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

Il terminale mostrerà:

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 Uso di uno script router

In questo esempio, le richieste per delle immagini le mostreranno, ma richieste per file HTML mostreranno "Welcome to PHP":

// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/'$_SERVER["REQUEST_URI"])) {
false;    // serve la risorsa richiesta così com'è.
} else { 
"<p>Welcome to PHP</p>";
$ php -S localhost:8000 router.php

Example #4 Controllo dell'Uso del Server Web CLI

Per riutilizzare uno script del router del framework durante lo sviluppo con il web server CLI e successivamente anche con un server web di produzione:

// router.php
if (php_sapi_name() == 'cli-server') {
/* route static assets and return false */
/* prosegue con le normali operazioni di index.php */
$ php -S localhost:8000 router.php

Example #5 Gestione Tipi File Non Supportati

Se si ha bisogno di restituire una risorsa statica il cui tipo MIME non viene gestito dal web server CLI, utilizzare:

// 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

Example #6 Accedere Al Web Server CLI Da Macchine Remote

È possibile rendere accessibile il web server sulla porta 8000 per qualsiasi interfaccia con:

$ php -S

Il server Web integrato non deve essere utilizzato su una rete pubblica.

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    www.example.com

2    cd [root folder]
    php -S www.example.com:8000

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.

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.
