PHP and CGI template engines: How to achieve website reusability
Introduction:
When developing websites, we often need to deal with the display of dynamic content. In order to achieve code maintainability and reusability, using a template engine is a wise choice. This article will introduce PHP and CGI, two commonly used template engines, and show how to use them to achieve website reusability through code examples.
1. PHP template engine
PHP is a widely used server scripting language with flexibility and powerful functions. The PHP template engine is a tool for embedding dynamic content in PHP code. The following are the steps to use the PHP template engine to achieve website reusability:

. Example (header.php
):
<!DOCTYPE html> <html> <head> <title>网站标题</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <header> <h1>网站名称</h1> </header>
include
and require
functions to achieve this purpose. Example (index.php
):
<?php include 'header.php'; ?> <main> <h2>欢迎访问我们的网站!</h2> <p>这是一个示例网页。</p> </main> <?php include 'footer.php'; ?>
Example (index.php
):
<?php $pageTitle = '首页'; $welcomeMessage = '欢迎访问我们的网站!'; include 'header.php'; ?> <main> <h2><?php echo $pageTitle; ?></h2> <p><?php echo $welcomeMessage; ?></p> </main> <?php include 'footer.php'; ?>
2. CGI Template Engine
CGI (Common Gateway Interface) is a A protocol for transferring data between servers and applications. Using the CGI template engine, we can achieve code maintainability and reusability in website development. The following are the steps to use the CGI template engine to achieve website reusability:
[%
and %]
to embed dynamic content. Example (header.tmpl
):
<!DOCTYPE html> <html> <head> <title>网站标题</title> <link rel="stylesheet" type="text/css" href="style.css"> </head> <body> <header> <h1>网站名称</h1> </header>
Example (index.cgi
):
#!/usr/bin/perl use strict; use warnings; use Template; my $tt = Template->new(); my $vars = { pageTitle => '首页', welcomeMessage => '欢迎访问我们的网站!' }; $tt->process('header.tmpl', $vars) || die $tt->error(); print '<main>'; print '<h2>[% pageTitle %]</h2>'; print '<p>[% welcomeMessage %]</p>'; print '</main>';
Conclusion:
By using PHP or CGI template engines, we can combine dynamic content with the website's Separation of layout and style. Doing so improves the maintainability and reusability of your code. Whether you choose PHP or CGI template engines, we can achieve website reusability through simple operations and code examples.
