As of PHP 5.4.0, the CLI SAPI provides a built-in web server.
This web server is designed for developmental purposes only, and should not be used in production.
Requests are served sequentially.
URI requests are served from the current working directory where PHP was started, unless the -t option is used to specify an explicit document root. If a URI request does not specify a file, then either index.php or index.html in the given directory are returned. If neither file exists, then a 404 response code is returned.
If a PHP file is given on the command line when the web server is
started it is treated as a "router" script. The script is run at
the start of each HTTP request. If this script returns FALSE,
then the requested resource is returned as-is. Otherwise the
script's output is returned to the browser.
Standard MIME types are returned for files with extensions: .css, .gif, .htm, .html, .jpe, .jpeg, .jpg, .js, .png, .svg, and .txt. The .htm and .svg extensions are recognized from PHP 5.4.4 onwards.
Example #1 Starting the web server
$ cd ~/public_html $ php -S localhost:8000
The terminal will show:
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
After URI requests for http://localhost:8000/ and http://localhost:8000/myscript.html the terminal will show something similar to:
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
Example #2 Starting with a specific document root directory
$ cd ~/public_html $ php -S localhost:8000 -t foo/
The terminal will show:
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 Using a Router Script
In this example, requests for images will display them, but requests for HTML files will display "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
Example #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:
<?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
Example #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:
<?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
Example #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 0.0.0.0:8000
