[PHP][] is a server-side programming language that is used in conjunction with [HTML][] to enhance the features of a website. It can be used to add a log-in screen or a survey, [redirect visitors][], create a calendar, send and receive cookies, and more. If your website is already published on the web, you'll need to alter it a bit to use the PHP code with the page.

[PHP][]是一种服务器端编程语言，与[HTML][]结合使用可增强网站的功能。 它可用于添加登录屏幕或调查， [重定向访问者][redirect visitors] ，创建日历，发送和接收Cookie等等。 如果您的网站已经发布在网络上，则需要对其进行一些更改以在页面上使用PHP代码。

When a webpage is accessed, the server checks the extension to know how to handle the page. Generally speaking, if it sees a .htm or .html file, it sends it right to the browser because it doesn't have anything to process on the server. If it sees a .php extension, it knows that it needs to execute the appropriate code before passing it along to the browser.

当访问网页时，服务器检查扩展名以知道如何处理该页面。 一般而言，如果看到.htm或.html文件，则会将其直接发送给浏览器，因为它在服务器上没有任何要处理的内容。 如果它看到一个.php扩展名，则表明它需要执行适当的代码，然后才能将其传递给浏览器。

## 处理 **(** Process **)** ##

You find the perfect script, and you want to run it on your website, but you need to include PHP on your page for it to work. You could just rename your pages to yourpage.php instead of yourpage.html, but you may already have incoming [links][] or search engine ranking, so you don't want to change the file name. What can you do?

您找到了理想的脚本，并且想要在您的网站上运行它，但是您需要在页面上包含PHP才能使其正常工作。 您可以将页面重命名为yourpage.php而不是yourpage.html，但是您可能已经具有传入[链接][links]或搜索引擎排名，因此您不想更改文件名。 你能做什么？

If you are creating a new file anyway, you may as well use .php, but the way to execute PHP on a .html page is to modify the .htaccess file. This file may be hidden, so depending upon your FTP program, you may have to modify some settings to see it. Then you just need to add this line for .html:

如果仍在创建新文件，则也可以使用.php，但是在.html页面上执行PHP的方法是修改.htaccess文件。 该文件可能是隐藏的，因此根据您的FTP程序，您可能必须修改一些设置才能看到它。 然后，您只需要为.html添加以下行：

AddType application/x-httpd-php .html

or for .htm:

或.htm：

AddType application/x-httpd-php .htm

If you only plan on including the PHP on one page, it is better to set it up this way:

如果仅计划将PHP包含在一页上，则最好通过以下方式进行设置：

<Files yourpage.html> AddType application/x-httpd-php .html </Files>

This code makes the PHP executable only on the yourpage.html file and not on all of your HTML pages.

此代码使PHP仅在yourpage.html文件上可执行，而不在所有HTML页面上可执行。

## 陷阱 **(** Pitfalls **)** ##

*  If you have an existing .htaccess file, add the supplied code to it, do not overwrite it or other settings may stop working. Always be cautious when working on your .htaccess file and ask your host if you need help.
    
    如果您有现有的.htaccess文件，请向其添加提供的代码，请勿覆盖它，否则其他设置可能会停止工作。 处理.htaccess文件时，请始终保持谨慎，并询问主机是否需要帮助。
 *  Anything in your .html files that starts with <? will now be executed as PHP, so if it's in your file for some other reason (as an XML tag, for example), you need to echo these lines to prevent errors. For example, use: <?php echo '<?xml version="1.0" encoding="IUTF-8"?>'; ?>
    
    您.html文件中以<？开头的所有内容？ 现在将作为PHP执行，因此，如果由于其他原因(例如，作为XML标签)在文件中，则需要回显这些行以防止错误。 例如，使用：<？php echo'<？xml version =“ 1.0” encoding =“ IUTF-8”？>'; ？>
