PHP for loop Exercises : Iterating on two integers to get Fizz, Buzz and FizzBuzz

PHP for loop: Exercise-11 with Solution

Write a PHP program which iterates the integers from 1 to 100. For multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz".

Sample Solution:

PHP Code:

<?php
// Loop through numbers from 1 to 100
for ($i = 1; $i <= 100; $i++)
{
    // Check if the number is divisible by both 3 and 5
    if ($i % 3 == 0 && $i % 5 == 0)
    {
        // Print FizzBuzz if divisible by both 3 and 5
        echo $i . " FizzBuzz" . "\n";
    }
    // Check if the number is divisible by 3 only
    else if ($i % 3 == 0)
    {
        // Print Fizz if divisible by 3 only
        echo $i . " Fizz" . "\n";
    }
    // Check if the number is divisible by 5 only
    else if ($i % 5 == 0)
    {
        // Print Buzz if divisible by 5 only
        echo $i . " Buzz" . "\n";
    }
    // If the number is not divisible by 3 or 5
    else
    {
        // Print the number itself
        echo $i . "\n";
    }
}
?>

Output:

1                                                           
2                                                           
3 Fizz                                                      
4                                                           
5 Buzz                                                      
6 Fizz                                                      
7                                                           
8                                                           
9 Fizz                                                      
10 Buzz                                                     
......                                                
90 FizzBuzz                                                 
91                                                          
92                                                          
93 Fizz                                                     
94                                                          
95 Buzz                                                     
96 Fizz                                                     
97                                                          
98
99 Fizz                                                     
100 Buzz

Explanation:

In the exercise above,

• The code starts with a PHP opening tag <?php.
• It enters a "for" loop that iterates through numbers from 1 to 100 (for ($i = 1; $i <= 100; $i++)).
• Inside the loop, there are several conditional statements.
• It first checks if the current number is divisible by both 3 and 5 (if ($i % 3 0 && $i % 5 0)).
• If it is divisible by both, it echoes "FizzBuzz".
• If not, it checks if the number is divisible by 3 only (else if ($i % 3 == 0)).
• If it is divisible by 3 only, it echoes "Fizz".
• Next, it checks if the number is divisible by 5 only (else if ($i % 5 == 0)).
• If it is divisible by 5 only, it echoes "Buzz".
• If the number is not divisible by either 3 or 5, it simply echoes the number itself.
• After evaluating the conditions for each number in the loop, the code proceeds to the next iteration.
• Once all numbers from 1 to 100 have been processed, the loop ends, and the PHP code closes with ?>.
