1. Write a program in Php to check whether a number is prime or not?
The program in Php to check whether a number is prime or not is as follows :
<?php
function primeCheck($number){
if ($number == 1)
return 0;
for ($i = 2; $i <= $number/2; $i++){
if ($number % $i == 0)
return 0;
}
return 1;
}
$number = 31;
$flag = primeCheck($number);
if ($flag == 1)
echo "Prime";
else
echo "Not Prime"
?>
2. Write a program to find no of days between two dates in Php?
//Let the dates are 25-09-2020 and 31-01-2021
<?php
function dateDiffInDays($date1, $date2)
{
$diff = strtotime($date2) - strtotime($date1);
return abs(round($diff / 86400));
}
$date1 = "25-09-2020";
$date2 = "31-01-2021";
$dateDiff = dateDiffInDays($date1, $date2);
printf("Difference between two dates: ". $dateDiff . " Days ");
?>
3. Write a program in PHP to find the occurrence of a word in a string?
<?php
$s1 = "interviewmocks.com is a interview prep site";
$s2 = "interview";
$res = substr_count($s1, $s2);
echo($res);
?>

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;

function Palindrome($number){
$temp = $number;
$new = 0;
while (floor($temp)) {
$d = $temp % 10;
$new = $new * 10 + $d;
$temp = $temp/10;
}
if ($new == $number){
return 1;
}
else{
return 0;
}
}
$original = 257752;
if (Palindrome($original)){
echo "Palindrome";
}
else {
echo "Not a Palindrome";
}
?>
6 . Write a program to find the factorial of a number in PHP?
<?php
function Factorial($number){
if($number <= 1){
return 1;

}
$number = 20;
$fact = Factorial($number);
echo "Factorial = $fact";
?>

<?php
function armstrongCheck($number){
$sum = 0;
$x = $number;
while($x != 0)
{
$rem = $x % 10;
$sum = $sum + $rem*$rem*$rem;
$x = $x / 10;
}
if ($number == $sum)
return 1;
return 0;
}
$number = 153;
$flag = armstrongCheck($number);
if ($flag == 1)
echo "Yes";
else
echo "No"
?>

<?php
function Fibonacci($n){
$num1 = 0;
$num2 = 1;
$counter = 0;
while ($counter < $n){
echo ' '.$num1;
$num3 = $num2 + $num1;
$num1 = $num2;
$num2 = $num3;
$counter = $counter + 1;
}
}
$n = 10;
Fibonacci($n);
?>

$revnum = 0;
while ($num > 1)
{
$rem = $num % 10;

}
echo "Reverse number of 79658 is: $revnum";
?>
