Are there any best practices for displaying PHP code without colors in a web application?

When displaying PHP code without colors in a web application, it's important to ensure that the code is still easily readable and distinguishable from other content on the page. One way to achieve this is by using a monospace font for the code and adding line numbers for reference. Additionally, you can indent the code to improve readability.

<pre>
<code style="font-family: monospace;">
<?php
// Your PHP code goes here
?>
</code>
</pre>
