When writing PHP code in the browser, how can I only display the code without executing it?

When writing PHP code in the browser, usually we want to only display the code without executing it. This need is mainly to show code examples without letting the browser interpret and execute PHP code. In actual development, we can achieve this goal in some simple ways.

A common method is to use the HTML <div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"></pre><div class="contentsignin">Copy after login</div></div><div class="contentsignin">Copy after login</div></div> tag, which retains the formatting of the code and displays it as preformatted text without interpreting the HTML or PHP code within it. .

Another method is to use PHP's highlight_file function, which will highlight the PHP code in the specified file and output it to the browser without executing it. PHP code.

Below I will show specific code examples of these two methods respectively:

Using HTML's `<div class="code" style="position:relative; padding:0px; margin:0px;"><div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"></pre><div class="contentsignin">Copy after login</div></div><div class="contentsignin">Copy after login</div></div>` tag

<!DOCTYPE html>
<html>
<head>
    <title>显示PHP代码示例</title>
</head>
<body>
    <pre class="brush:php;toolbar:false">
        <?php
        // 这里写PHP代码示例
        echo "Hello, World!";
        ?>

Copy after login

above In the code, the <div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false"></code> tag contains PHP code examples. The browser will display the code as it is and will not execute the PHP code. </p><h3>Using PHP's <code>highlight_file</code> function </h3><pre class='brush:php;toolbar:false;'><?php highlight_file("example.php"); ?></pre><div class="contentsignin">Copy after login</div></div><p>In the above code, the <code>highlight_file function will highlight the PHP code in the specified file, and output to the browser. Make sure the example.php file contains the PHP code example you want to show.

With the above two methods, we can display PHP code samples in the browser without executing the code. This is very useful for teaching examples, code demonstrations, etc.
