Q1. Write a PHP program to count the number of vowels in a string.
Ans: PROGRAM NO. - 1 =>
<?php
$str="Welcome To Capgemini";
$vow=0;
$str=str_replace(" ", "", $str);
$len=strlen($str);
for ($j=0; $j < $len; $j++) {
if ($str[$j] == "a" || $str[$j] == "e" || $str[$j] == "i" || $str[$j] == "o" || $str[$j] == "u" || $str[$j] == "A" || $str[$j] == "E" || $str[$j] == "I" || $str[$j] == "O" || $str[$j] == "U") {
$vow++;
}
}
print_r("The number of vowels in a string is: ".$vow);
?>

PROGRAM NO. - 2 =>
<?php
$str="Welcome To Pitangent";
$vow=0;
$str=str_replace(" ", "", $str);
$length=strlen($str);
for ($i=0; $i < $length; $i++) {
if ($str[$i] == 'a' || $str[$i] == 'e' || $str[$i] == 'i' || $str[$i] == 'o' || $str[$i] == 'u' || $str[$i] == 'A' || $str[$i] == 'E' || $str[$i] == 'I' || $str[$i] == 'O' || $str[$i] == 'U') {
$vow++;
}
}
print_r("The number of vowels in a string is: ".$vow."<br>");
?>

Q2. Write a PHP code to check whether a number is prime or not.
Ans: PROGRAM NO. - 1 =>
<?php
function isPrime($num){
if ($num <= 1) {
return false;
}
for ($i=2; $i <= sqrt($num); $i++) {
if ($num%$i==0) {
return false;
}
}
return true;
}
$number=19;
if (isPrime($number)) {
echo "$number is a prime number"."<br>";
}
else{
echo "$number is not a prime number";
}
?>
