Combining PHP with HTML: three techniques for embedding code
The combination of PHP and HTML is a common technology in web development. Through PHP, dynamic content can be embedded in HTML files and auxiliary functions can be implemented, which greatly improves the interactivity and functionality of the website. Customizability. This article will introduce three techniques for embedding code and provide specific code examples for reference.
1. Use PHP tags to embed code
The most common way is to use PHP tags () to embed PHP code into HTML files to display dynamic content. For example, you can use PHP to obtain the system time and display it on the web page:
<!DOCTYPE html>
<html>
<head>
<title>显示系统时间</title>
</head>
<body>
<h1 id="当前系统时间是-php-echo-date-Y-m-d-H-i-s">当前系统时间是：<?php echo date('Y-m-d H:i:s'); ?></h1>
</body>
</html>In the above code, the system time is obtained through PHP's date function and displayed on the page, achieving a dynamic effect.
2. Use PHP to embed HTML code
In addition to embedding code in PHP tags, you can also write HTML code directly in PHP code. This method is more suitable for more complex logic processing. For example, a table can be generated through PHP loop statements:
<!DOCTYPE html>
<html>
<head>
<title>动态生成表格</title>
</head>
<body>
<table>
<tr>
<?php for($i = 1; $i <= 5; $i++): ?>
<td>第<?php echo $i; ?>列</td>
<?php endfor; ?>
</tr>
</table>
</body>
</html>In the above code, a 5-column table is generated through PHP's for loop, and the corresponding column number is displayed in each column.
3. Embed code using included files
In order to improve the maintainability and reusability of the code, you can extract some public parts and embed them into HTML files by including files. For example, you can extract the header and footer portions of your website:
header.php:
<!DOCTYPE html>
<html>
<head>
<title>网站标题</title>
</head>
<body>
<header>
<h1 id="网站标题">网站标题</h1>
<nav>
<a href="#">首页</a>
<a href="#">关于我们</a>
<a href="#">联系我们</a>
</nav>
</header>footer.php:
<footer>
<p>© 2022 网站版权所有</p>
</footer>
</body>
</html>index.php:
<?php include 'header.php'; ?>
<section>
<h2 id="欢迎访问">欢迎访问</h2>
<p>这是一个简单的网站示例。</p>
</section>
<?php include 'footer.php'; ?>In the above code, header.php and footer.php are included into index.php through the include statement, realizing the reuse of the header and tail.
To sum up, through the above three techniques of embedding codes, you can flexibly combine PHP and HTML to achieve feature-rich and dynamic web page effects. In actual development, choose the appropriate method for code embedding according to specific needs to improve development efficiency and website user experience.

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
