PHP Solved slips

Slip 1: 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’ construct or 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:

Slip 2: Write a PHP script for the following: Design a form to accept two strings from the user. Find the first occurrence and the last occurrence of the small string in the large string. Also count the total number of occurrences of small string in the large string. Provide a text box to accept a string, which will replace the small string in the large string. (Use built-in functions)

Slip 3: Write a PHP script for the following: Design a form to accept two numbers from the user. Give options to choose the arithmetic operation (use radio buttons). Display the result on the next form. (Use the concept of function and default parameters. Use ‘include’ construct or require stmt).
