PHP vs. HTML
Introduction
HTML is a markup language, while PHP is a scripting language. HTML is used to create the structure and content of web pages, while PHP is used to program the functionality and behavior of web pages.
Syntax
HTML has a set of predefined tags and attributes that are used to describe the structure of web pages. The following is an example of HTML code:
<!DOCTYPE html>
<html>
<head>
<title>My Web Page</title>
</head>
<body>
<h1>Welcome to my web page</h1>
<p>This is a paragraph of text.</p>
</body>
</html>
PHP code, on the other hand, is embedded within HTML code, denoted by tags. The following is an example of PHP code:
<!DOCTYPE html>
<html>
<head>
<title>My Web Page</title>
</head>
<body>
<h1>Welcome to my web page</h1>
<p><?php echo "This is a paragraph of text."; ?></p>
</body>
</html>
Explanation
HTML is static and does not change based on user input unless it is modified manually, while PHP can create dynamic web pages that change based on user input and other factors.
HTML only describes the structure of web pages, while PHP can be used to program the functionality and behavior of web pages, such as processing form data, querying databases, and manipulating files.
Use
HTML is still needed to create the basic structure and content of web pages, while PHP is used to add more complex functionality and interactivity to web pages.
In general, HTML is used to create the user interface of a web page, while PHP is used to provide the behind-the-scenes logic that makes the web page function as intended.
Important Points
- HTML cannot create dynamic web pages, while PHP can.
- PHP can be embedded within HTML code, but HTML cannot be embedded within PHP code.
- HTML is used to create the structure and content of web pages, while PHP is used to program the behavior and functionality of web pages.
Summary
HTML and PHP are both critical components of creating web pages. HTML provides the structure and content of a web page, while PHP adds the functionality and interactivity. Understanding the differences between the two languages can help you create effective and dynamic web pages.
