Course Name: Web Application Development using PHP

Course Code: DSC-M-BCA-354 P

Credits: 4
Course Outcomes:

The aim of this course is to enable students to

 Get familiar with server-side language for web development.


 Learn basic concepts of PHP, functions for database operations using MySQL.
 Learn about AJAX in PHP for faster processing of web applications.
 Get familiar with validations.

Prerequisites:

 Basic knowledge of data types, HTML tags.

Unit-1 1. Write a PHP program to check whether the number entered


Basic Programs is Positive / Negative or Zero entered by user.
2. Write a PHP program to find maximum number from the two
numbers entered by user
3. Write a PHP program that prints Fibonacci series till the
number entered by user.
4. Accept a string from user. Write PHP program to check
whether that entered string is palindrome or not.
5. Write a PHP program to accept a number from user and find
its square and cube.
6. Write a PHP program to find sum of n numbers. Take input
from user.
7. Accept a two numbers from user. Write a PHP program to
Add, Subtract and Multiply the numbers and displays result.
8. Accept a number from user as “Radius” of a circle. Write PHP
program find Area of a Circle. ( Area = PI * radius * radius).
9. Write a PHP program to print all even numbers till the
entered number.
10. Create a function that accepts 3 numbers as parameters and
check whether the sum of 3 numbers is prime or not. Note:
Input should be collected from user using an HTML page.
11. Create a function that accepts a number as argument and
displays sum of digit of a number. E.g. If Number is 123 then
sum of Digits is 6 i.e., 1+2+3 =6 Note: Input should be
collected from user using an HTML page.
12. Write a PHP program that changes color of the web page
