How can PHP developers ensure that HTML code is displayed correctly without any character replacements?

To ensure that HTML code is displayed correctly without any character replacements, PHP developers can use the htmlentities function to encode special characters in the HTML code. This function will convert characters like <, >, ", ', and & into their corresponding HTML entities, ensuring that the code is displayed as intended without any interference from the browser. 

&lt;?php
$html_code = &quot;&lt;h1&gt;Hello, World!&lt;/h1&gt;&quot;;
echo htmlentities($html_code);
?&gt;
