PHP 5.4 built-in web server_PHP tutorial

PHP is a scripting language, which requires a PHP interpreter to analyze and run PHP files. When using PHP as a CGI to serve web requests, it needs to be embedded into some kind of web server, most commonly integrated into Apache or IIS. This means that before using PHP, you need to install Apache or IIS, and Correctly configure them and PHP integration parameters. Although this configuration has been standardized and the documentation is very rich, we still often encounter problems when installing the integration of Apache and PHP. Moreover, sometimes we just want to test a simple PHP feature and do not want to install and start the Apache service for this purpose. .

But according to the official documentation, this built-in web server is only for development and testing, and is not recommended for use in production environments. Because this server accepts and processes requests sequentially and cannot handle them concurrently.

This built-in web server is very convenient to use, you only need to execute the following command:

1. <span><span>$ php -S localhost:8000 </span></span>

Then you can access it. After starting in this way, the default web service directory is the current directory where the command is executed. If you do not want to use the current directory, you need to use the -t parameter to specify it.

Example #1 Start Web Server

1. <span><span>$ cd ~/public_html  </span></span>

2. $ php -S localhost:8000

Terminal output information:

1. <span><span>PHP 5.4.0 Development Server started at Thu Jul 21 10:43:28 2011  </span></span>

2. Listening on localhost:8000
3. Document root is /home/me/public_html
4. Press Ctrl-C to quit

After requesting the http://localhost:8000/ and http://localhost:8000/myscript.html addresses, the terminal outputs information similar to the following:

1. <span><span>PHP 5.4.0 Development Server started at Thu Jul 21 10:43:28 2011  </span></span>

2. Listening on localhost:8000
3. Document root is /home/me/public_html
4. Press Ctrl-C to quit.
5. [Thu Jul 21 10:48:48 2011] ::1:39144 GET /favicon.ico - Request read
6. [Thu Jul 21 10:48:50 2011] ::1:39146 GET / - Request read
7. [Thu Jul 21 10:48:50 2011] ::1:39147 GET /favicon.ico - Request read
8. [Thu Jul 21 10:48:52 2011] ::1:39148 GET /myscript.html - Request read
9. [Thu Jul 21 10:48:52 2011] ::1:39149 GET /favicon.ico - Request read

Example #2 Specify the root directory of the document when starting the web server

1. <span><span>$ cd ~/public_html  </span></span>

2. $ php -S localhost:8000 -t foo/

Terminal display information:

1. <span><span>PHP 5.4.0 Development Server started at Thu Jul 21 10:50:26 2011  </span></span>

2. Listening on localhost:8000
3. Document root is /home/me/public_html/foo
4. Press Ctrl-C to quit

If you append a php script file to the startup command line, this file will be treated as a "router" script. This script will be responsible for all HTTP requests. If this script returns FALSE when executed, the requested resource will be returned normally. If it is not FALSE, the content generated by this script will be displayed in the browser.

Example #3 Using Router Script

In this example, a request for an image returns the corresponding image, but a request for an HTML file displays "Welcome to PHP":

2. <span class="comment">// router.php </span><span> </span>

3. if (preg_match('/.(?:png|jpg|jpeg|gif)$/', $_SERVER["REQUEST_URI"])) {
4. return false; } else
{
5. echo
"
6. Welcome to PHP ";  
7. }  
8. ?> 

1. <span><span>$ php -S localhost:8000 router.php </span></span>

例 #4 判断是否是在使用内置web服务器

通过程序判断来调整同一个PHP路由器脚本在内置Web服务器中和在生产服务器中的不同行为：

2. <span class="comment">// router.php </span><span> </span>

3. if (php_sapi_name() == 'cli-server') {  
4. /* route static assets and return false */ 
5. }  
6. /* go on with normal index.php operations */ 
7. ?> 

1. <span><span>$ php -S localhost:8000 router.php </span></span>

这个内置的web服务器能识别一些标准的MIME类型资源，它们的扩展有：.css, .gif, .htm, .html, .jpe, .jpeg, .jpg, .js, .png, .svg, and .txt。对.htm 和 .svg 扩展到支持是在PHP 5.4.4之后才支持的。

例 #5 处理不支持的文件类型

如果你希望这个Web服务器能够正确的处理不被支持的MIME文件类型，这样做：

2. <span class="comment">// router.php </span><span> </span>

3. $path = pathinfo($_SERVER["SCRIPT_FILENAME"]);  
4. if ($path["extension"] == "ogg") {  
5. header("Content-Type: video/ogg");  
6. readfile($_SERVER["SCRIPT_FILENAME"]);  
7. }  
8. else {  
9. return FALSE;  
10. }  
11. ?> 

1. <span><span>$ php -S localhost:8000 router.php </span></span>

如果你希望能远程的访问这个内置的web服务器，你的启动命令需要改成下面这样：

例 #6 远程访问这个内置Web服务器

1. <span><span>$ php -S 0.0.0.0:8000 </span></span>

这样你就可以通过 8000 端口远程的访问这个内置的web服务器了
