1. Develop and demonstrate an HTML file that includes PHP script to generate first ‘n’ Fibonacci numbers
Fibonacci seris
Enter the limit: "; $c=$a+$b; } } ?>
2. Create a PHP script that accepts a number through inputbox and checks whether it is palindrome or not
Palindrom
Enter the number: php if(isset($_POST['sub'])) { $x=$_POST['n']; $r=0; $z=$x; while($x!=0) { $t=$x%10; $r=$r*10+$t; $x=intval($x/10); } if($z==$r) {
$len=strlen($string);
$num=0; for($i=0;$i<$len;$i++) { if(in_array($string[$i],$vowels)) { $num++; } } echo "Number of vowels: $num"; $len=$len-1; echo "Number of characters: $len"; $word=str_word_count($string); echo "Number of words: $word"; $line=substr_count($_POST['str'],"\n"); echo "Number of lines: $line"; } ?>
4. Develop a simple calculator web application that takes 2 numbers and an operator (+,-,, /,%) from an HTML page and returns the result.*
simple calculator
Enter the number:
Enter another number:
php if(isset($_POST['sub'])) { $num1=$_POST['num1']; $num2=$_POST['num2']; $fun=$_POST['fun']; if(is_numeric($num1) && is_numeric($num2)) { if($fun!=null) { switch($fun) { case "+":
Username:
session started at".date("h:i:sa",$tm).""; echo ""; echo "
"; echo ""; echo "Hello".$_SESSION['luser']; } ?>php
session_start();
date_default_timezone_set("Asia/Calcutta"); echo "
session started at".date("h:i:sa",time())."
"; echo "Thank you ".$_SESSION['luser'].""; $session_time=time()-$_SESSION['start']; echo "Session duration ".$session_time." seconds"; ?>6. Develop a web application that takes the name and age from an HTML page. If the age is less than 18, it should display a page with “hello , you are not authorized to visit this site” otherwise it should display the message, “, welcome to this site”.

{ $_SESSION['counter']=1; } echo "You have visited the page ".$_SESSION['counter']." time in this session"; ?>
8. Develop a database based web application that performs login validation and prints the corresponding message based on checking the username and password from MySQL database.
User Login
Username : Password :
php if(isset($_POST['sub'])) { $conn=new mysqli('localhost','root','','info');
if($conn->connect_errno)
{ echo "Failed to connect with the server"; exit(); } else { $uname=$_POST['uname']; $pass=$_POST['pass']; $q="select Message from users where Username='$uname' and Password='$pass'"; $result=$conn->query($q); if($result->num_rows>0) { $row=$result->fetch_assoc(); echo "Message ".$row['Message']; } else { echo "Either username or password is wrong"; } } } ?>
else
{ echo "Cookie is not set. You have to set cookie"; } ?>
10. Create a PHP script that reads an array and displays the array in sorted order.
Sorting an array
Enter the string:
php if(isset($_POST['sub'])) { $string=$_POST['str']; $x=strlen($string); $count=substr_count($string," "); $array=explode(" ",$string); for($i=0;$i<$count;$i++) { for($j=$i+1;$j<=$count;$j++)
if($array[$i]>$array[$j]) { $temp=$array[$i]; $array[$i]=$array[$j]; $array[$j]=$temp; } } } print_r($array); } ?>
11. Develop a web application that develops a student registration form and displays the entered details to another page
Student Registration Form
Name
Student Details
Name
Age
Gender
Date of Birth

Employee details
Employee department
Employee Name
$q="insert into empdet(dept,name,id,sal)values
('$edept','$ename','$eid','$esal')"; if($conn->query($q)===TRUE) { echo ""; } else die('error'); } ?>
Employee Details
Employee Department Employee Name Employee id Employee salary
connect_errno)
echo "Failed to connect with the server"; exit(); } $query="select * from empdet"; if($result=$conn->query($query)) { while($row=$result->fetch_assoc()) { echo ""; echo "".$row['dept'].""; echo "".$row['name'].""; echo "".$row['id'].""; echo "".$row['sal'].""; echo ""; } } $conn->close(); ?>
13. Create a database application in PHP that can delete a student record on accepting the enrolment number of the student. A message should be displayed on deletion of the record and the contents of the table should be displayed
