What are common methods for reading and displaying HTML code from a text file in PHP?

To read and display HTML code from a text file in PHP, you can use the file_get_contents() function to read the contents of the file into a variable, and then echo out the contents within a <pre> tag to preserve the formatting. This will display the HTML code as text on the webpage.

&lt;?php
$file = &#039;html_code.txt&#039;;
$html_code = file_get_contents($file);
echo &#039;&lt;pre&gt;&#039; . htmlspecialchars($html_code) . &#039;&lt;/pre&gt;&#039;;
