Solution:

HTML Code:

<!DOCTYPE html><!-- HTML5 document type declaration -->
<html><!-- Start of HTML document -->
<head><!-- Start of head section -->
<meta charset="utf-8"><!-- Declares document character encoding -->
<title>How to define additional details that the user can view or hide</title><!-- Sets the title of the webpage -->
</head><!-- End of head section -->
<body><!-- Start of body section -->
<details><!-- Details element for defining additional details -->
<summary>PHP is a server side scripting language</summary><!-- Summary element for displaying a summary of the details -->
<p>PHP is a general-purpose server-side scripting language originally designed for web development to produce dynamic web   
pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP   
processor module, which generates the web page document.</p><!-- Additional details content -->
</details><!-- End of details element -->
</body><!-- End of body section -->
</html><!-- End of HTML document -->

Explanation:

This HTML document starts with a doctype declaration indicating it's an HTML5 document.
Inside the <html> tags, the document structure begins.
The <head> section contains metadata about the document, such as character encoding and the title.
The <body> section is where the visible content of the webpage resides.
The <details> element defines additional details that the user can view or hide.
Inside the <details> element, there's a <summary> element for displaying a summary of the details, which the user can click to toggle the visibility of the details.
The <p> element contains the additional details content.
The HTML document ends with the closing </html> tag.
