Internet and Web Technology Lecture
Concept of HTML, JavaScript, and PHP
The Internet and Web Technology domain consists of three key technologies:
HTML (HyperText Markup Language) → Structure of Web Pages
JavaScript → Adds Interactivity
PHP (Hypertext Preprocessor) → Server-Side Scripting
HTML (HyperText Markup Language)
HTML is the foundation of web pages.
It is a markup language that defines the structure of a webpage using tags.
HTML is not a programming language (it does not support logic or functions).
Basic HTML Structure:
Tags used in HTML:
-
<h1>to<h6>→ Headings -
<p>→ Paragraph -
<a href="">→ Links -
<img src="">→ Images -
<table>→ Tables -
<form>→ User input forms
HTML alone cannot add interactivity. That’s where JavaScript comes in.
JavaScript (Client-Side Scripting Language)
JavaScript makes web pages dynamic and interactive.
Runs inside the browser (client-side).
Used for validations, animations, and event handling.
Example – JavaScript Alert Box:
Example – JavaScript Button Click Event:
JavaScript is often used with HTML & CSS to create interactive web pages.
To handle server-side tasks, we use PHP.
PHP (Hypertext Preprocessor)
PHP is a server-side scripting language.
Used for dynamic web pages, form handling, and database connections.
Runs on web servers (not in browsers).
Example – PHP Basic Code:
Example – PHP Form Handling:
process.php (Server-Side Processing)
PHP interacts with databases like MySQL for data storage.
Comparison of HTML, JavaScript, and PHP
| Feature | HTML | JavaScript | PHP |
|---|---|---|---|
| Type | Markup Language | Client-Side Scripting | Server-Side Scripting |
| Runs On | Browser | Browser | Server |
| Purpose | Structure | Interactivity | Backend Processing |
| Example Use | <h1>Title</h1> |
alert("Hello!") |
echo "Hello PHP"; |
Summary
HTML → Defines Structure of the Web Page.
JavaScript → Adds Interactivity (Runs on the browser).
PHP → Handles Server-Side Processing (Runs on the server).
