Q. Write a PHP script for the following: Design a form to accept a string. Write a function to count the total number of vowels (a,e,i,o,u) from the string. Show the occurrences of each vowel from the string. Check whether the given string is a palindrome or not, without using built-in function. (Use radio buttons and the concept of function. Use ‘include’ constructor require stmt.)
HTML File:
<html>
<body>
<form method="GET" action="ass1a1.php">
Enter the String : <input type="text" name="inputStr"><br>
<input type="submit" name="Submit">
</form>
</body>
</html>
PHP Function:
NOTE: PHP function is saved as "ass1a1.php"
<?php
$string = $_GET['inputStr'];
$vowels = array("a"=>0,"e"=>0,"i"=>0,"o"=>0,"u"=>0);
for($i=0; $i<strlen($string); $i++) {
if(strtolower($string[$i]) == 'a') {
++$cnt;
++$vowels['a'];
}
if(strtolower($string[$i]) == 'e') {
++$cnt;
++$vowels['e'];
}
if(strtolower($string[$i]) == 'i') {
++$cnt;
++$vowels['i'];
}
if(strtolower($string[$i]) == 'o') {
++$cnt;
++$vowels['o'];
}
if(strtolower($string[$i]) == 'u') {
++$cnt;
++$vowels['u'];
}
}
echo "<h1>Total number of vowels found : ".$cnt."<h1>";
echo "Occurence of 'a' : ".$vowels['a']."<br>";
echo "Occurence of 'e' : ".$vowels['e']."<br>";
echo "Occurence of 'i' : ".$vowels['i']."<br>";
echo "Occurence of 'o' : ".$vowels['o']."<br>";
echo "Occurence of 'u' : ".$vowels['u']."<br>";
$str=strrev($string);
$a=strlen($string);
$f=0;
for($j=0;$j<$a;$j++)
{
if($str[$j]==$string[$j])
{
$f=0;
}
else
{
$f=1;
break;
}
}
if($f==0)
{
echo"string is palindrome";
}
else
{
echo"string is not palindrome";
}
?>
Output:
Enter the string:
Final Output:
