PHP版本内容内置Web Server

  • 时间:2023-12-17 18:02:40 作者: znjz 阅读:426

CLI SAPI 提供了一个内置的Web服务器。

这个内置的Web服务器主要用于本地开发使用,不可用于线上产品环境。

URI请求会被发送到PHP所在的的工作目录(Working Directory)进行处理,除非你使用了-t参数来自定义不同的目录。

如果请求未指定执行哪个PHP文件,则默认执行目录内的index.php 或者 index.html。如果这两个文件都不存在,服务器会返回404错误。

当你在命令行启动这个Web Server时,如果指定了一个PHP文件,则这个文件会作为一个“路由”脚本,意味着每次请求都会先执行这个脚本。如果这个脚本返回 false ,那么直接返回请求的文件(例如请求静态文件不作任何处理)。否则会把输出返回到浏览器。

示例 #1 启动Web服务器

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

终端窗口会显示:

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

接着访问http://localhost:8000/和http://localhost:8000/mysc ript.html,窗口会显示:

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 /mysc ript.html - Request read
[Thu Jul 21 10:48:52 2011] ::1:39149 GET /favicon.ico - Request read

示例 #2 启动时指定根目录

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

终端窗口显示:

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

示例 #3 使用路由(Router)脚本

请求图片直接显示图片,请求HTML则显示“Welcome to PHP”

<?php
// router.php
if (preg_match('/\.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"]))
return
false; // 直接返回请求的文件
else {
echo
"<p>Welcome to PHP</p>";
}
?>
$ php -S localhost:8000 router.php

执行之后终端显示:

PHP 5.4.0 Development Server started at Thu Jul 21 10:53:19 2011
Listening on localhost:8000
Document root is /home/me/public_html
Press Ctrl-C to quit.
[Thu Jul 21 10:53:45 2011] ::1:55801 GET /mylogo.jpg - Request read
[Thu Jul 21 10:53:52 2011] ::1:55803 GET /abc.html - Request read
[Thu Jul 21 10:53:52 2011] ::1:55804 GET /favicon.ico - Request read

示例 #4 Checking for CLI Web Server Use

To reuse a fr amework router sc ript 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

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

示例 #6 Accessing the CLI Web Server From Remote Machines

You can make the web server accessible on port 8000 to any interface with:
