How can PHP be used to toggle between displaying HTML code as text and rendering it as actual HTML content?

To toggle between displaying HTML code as text and rendering it as actual HTML content in PHP, you can use a conditional statement to check a variable or a parameter in the URL. If the variable is set to a specific value, you can use htmlentities() function to display the HTML code as text. If not, you can simply echo the HTML code to render it as actual content. 

<?php
// Check if a parameter named 'display' is set in the URL
if(isset($_GET['display']) && $_GET['display'] == 'text'){
    // Display HTML code as text
    $htmlCode = "<h1>Hello, World!</h1>";
    echo htmlentities($htmlCode);
} else {
    // Render HTML content
    echo "<h1>Hello, World!</h1>";
}
?>
