How to write PHP code in the browser and display only the code?

In today's technologically advanced age, learning how to write PHP code in a browser and just display the code is a very useful skill. In the world of web development, PHP is a popular server-side scripting language used by many websites and applications to generate dynamic content and interactivity. This article will introduce how to write PHP code in the browser and only display the code, while providing some specific code examples to help readers better understand.

First of all, make sure you have installed web server software on your computer, such as commonly used Apache, Nginx, etc. These software allow you to set up a server environment locally to execute PHP code in the browser.

Next, create a new PHP file named display_code.php and write the following code in it:

<?php
// 开启PHP代码
highlight_file(__FILE__);
// 显示该PHP文件的内容
?>

In this code, highlight_file(__FILE__)The function can display the code of the current PHP file in the browser in the form of syntax highlighting. This allows you to see the format and content of the code in the browser instead of executing the code directly.

Save this file and place it in the root directory of the web server or the virtual host directory you set. Next, enter the address http://localhost/display_code.php in the browser, and you can see the effect of the code.

In addition to displaying the code of the current file, you can also display the code of other PHP files by modifying the path parameters. For example, if you want to display the code of the example.php file, you can enter http://localhost/display_code.php?file=example.php in the URL.

In short, displaying PHP code in the browser in this way can help you better understand and debug the code, and it is also a good way to share and learn. Hope the above content is helpful to you!
