With the development of the Internet, web design has increasingly become an important profession in modern society. But it is not enough to just use HTML when designing a web page, because PHP is needed when the web page needs to interact with the server. Therefore, in web development, the technology of converting HTML to PHP files is very important.

Why do you need to convert HTML to PHP files?

HTML files are static and data cannot be transferred to the server for processing. If you only use HTML files, every time the user submits the form, all the content must be re-entered. And this is far inferior to using PHP files to achieve more convenient and complex interactions.

The PHP file is dynamic and can send data to the server for syntax parsing, data processing, database operations, etc., providing a continuous and interactive experience for web development.

How to convert HTML to PHP file?

To use PHP files instead of HTML files, you need to convert the static content in the HTML file into dynamic PHP code and store it in a file with a .php extension. Here is a simple example:

<!DOCTYPE html>
<html>
<head><title>转换为PHP文件示例</title></head>
<body>
<form method="POST" action="submit.php">
  <input type="text" name="username" placeholder="用户名" required>
  <input type="email" name="email" placeholder="电子邮件" required>
  <textarea name="message" placeholder="你的信息" required></textarea>
  <button type="submit">提交</button>
</form>
</body>
</html>

Copy after login

This is a basic HTML form that when submitted by the user needs to send data to the server for processing. In order to convert this into a PHP file, we need to set the action attribute to submit.php:

<!DOCTYPE html>
<html>
<head><title>转换为PHP文件示例</title></head>
<body>
<form method="POST" action="submit.php">
  <input type="text" name="username" placeholder="用户名" required>
  <input type="email" name="email" placeholder="电子邮件" required>
  <textarea name="message" placeholder="你的信息" required></textarea>
  <button type="submit">提交</button>
</form>
</body>
</html>

Copy after login

In the same directory, we can create a submit.php file that will handle the form data. Here is the content of a sample submit.php file:

<?php 
if(isset($_POST[&#39;username&#39;]) && isset($_POST[&#39;email&#39;]) && isset($_POST[&#39;message&#39;])){ 
  $username = $_POST[&#39;username&#39;];
  $email = $_POST[&#39;email&#39;];
  $message = $_POST[&#39;message&#39;]; 
  echo "欢迎来到网站， $username ，你的电子邮件是 $email ，你的信息是： $message ！"; 
} 
else{ 
  echo "对不起，表单数据未提交。"; 
} 
?>

Copy after login

This file will take the form data and display a message to remind the user to enter and display the form data.

Summary

HTML conversion to PHP files is one of the basic operations in web development. It can make web pages dynamic, interactive and real-time. In web design, converting HTML code to PHP code can help you implement complex interactions and data exchanges, providing a better experience for end users.
