?>
HTML Basics
HTML forms the foundation of web development, providing the structure and content for webpages. Regardless of the programming language used, HTML plays a crucial role in creating web content. Let’s explore some essential aspects of HTML:
Tags
HTML uses tags to define elements and their characteristics. These tags are enclosed within angle brackets (< >) and provide structure to the content. Each tag serves a specific purpose, such as defining headings, paragraphs, lists, images, and links.
Attributes
HTML tags can include attributes that provide additional information or behavior to the elements. Attributes define attributes such as the source of an image, the hyperlink destination, or the style of an element.
Structure
HTML follows a hierarchical structure using elements like <head>, <body>, <header>, <footer>, <div>, and more. These elements help organize the content and provide meaning to the webpage structure.
Forms
HTML forms enable user input and interaction on webpages. Developers can create forms with various input types, including text fields, checkboxes, radio buttons, and dropdown menus. These forms facilitate data submission and interaction with backend systems.
Here’s an example of HTML code that showcases the basic structure and a simple form:
<!DOCTYPE html>
<html>
<head>
<title>My Website</title>
</head>
<body>
<h1>Welcome to My Website</h1>
<p>This is a paragraph of text.</p>
<form action=”submit.php” method=”POST”>
<input type=”text” name=”username” placeholder=”Enter your username”>
<input type=”password” name=”password” placeholder=”Enter your password”>
<input type=”submit” value=”Submit”>
</form>
</body>
</html>
Advantages of PHP
PHP offers several advantages that make it a powerful technology for web development. Let’s explore some of its key benefits:
Server-Side Processing
One of the significant advantages of PHP is that it is executed on the server-side. This feature enhances security and efficiency, as sensitive data and complex operations are handled server-side, reducing the risk of exposing critical information.
