PHP Exercises: Check whether a given string starts with "F" or ends with "B"
PHP Basic Algorithm: Exercise-45 with Solution
Write a PHP program to check whether a given string starts with "F" or ends with "B". If the string starts with "F" return "Fizz" and return "Buzz" if it ends with "B" If the string starts with "F" and ends with "B" return "FizzBuzz". In other cases return the original string.
Sample Solution:
PHP Code :
<?php
// Define a function that checks the given string for specific conditions and returns corresponding values
function test($s)
{
// Check if the first character is "F" AND the last character is "B"
// If true, return "FizzBuzz"
if ((substr($s, 0, 1) == "F") && (substr($s, strlen($s) - 1, 1) == "B")) {
return "FizzBuzz";
}
// Check if the first character is "F"
// If true, return "Fizz"
else if (substr($s, 0, 1) == "F") {
return "Fizz";
}
// Check if the last character is "B"
// If true, return "Buzz"
else if (substr($s, strlen($s) - 1, 1) == "B") {
return "Buzz";
}
// If none of the conditions are met, return the original string
else {
return $s;
}
}
// Test the function with different strings
echo test("FizzBuzz")."\n";
echo test("Fizz")."\n";
echo test("Buzz")."\n";
echo test("Founder")."\n";
?>
Sample Output:
Fizz Fizz Buzz Fizz
