Today I was bored as hell, so I decided to implement the (in)famous "FizzBuzz" test using PHP, and bellow are the results (boring as hell too, I know!). Also, looking for information about "Recursion" in PHP I found this interesting
tutorial from
Devzone.Zend.com:
<?php // Return the PHP version of the FizzBuzz test results: for (
$i = 1;
$i < 101;
$i++) {
if (
$i%3 == 0 &&
$i%5 == 0) {
echo 'FizzBuzz (' .
$i .
'), ';
}
elseif (
$i%3 == 0) {
echo 'Fizz (' .
$i .
'), ';
}
elseif (
$i%5 == 0) {
echo 'Buzz (' .
$i .
'), ';
}
else {
echo $i;
}
}
?> // The FizzBuzz test results:1, 2, Fizz (3), 4, Buzz (5), Fizz (6), 7, 8, Fizz (9), Buzz (10), 11, Fizz (12), 13, 14, FizzBuzz (15),
16, 17, Fizz (18), 19, Buzz (20), Fizz (21), 22, 23, Fizz (24), Buzz (25), 26, Fizz (27), 28, 29, FizzBuzz (30),
31, 32, Fizz (33), 34, Buzz (35), Fizz (36), 37, 38, Fizz (39), Buzz (40), 41, Fizz (42), 43, 44, FizzBuzz (45),
46, 47, Fizz (48), 49, Buzz (50), Fizz (51), 52, 53, Fizz (54), Buzz (55), 56, Fizz (57), 58, 59, FizzBuzz (60),
61, 62, Fizz (63), 64, Buzz (65), Fizz (66), 67, 68, Fizz (69), Buzz (70), 71, Fizz (72), 73, 74, FizzBuzz (75),
76, 77, Fizz (78), 79, Buzz (80), Fizz (81), 82, 83, Fizz (84), Buzz (85), 86, Fizz (87), 88, 89, FizzBuzz (90),
91, 92, Fizz (93), 94, Buzz (95), Fizz (96), 97, 98, Fizz (99), Buzz (100),
<?php// Recursive factorial functionfunction factorial(
$number) {
if (
$number < 0 || !is_int(
$number)) {
return 'NULL: Negative numbers and strings aren't allowed!';
}
if (
$number < 2) {
return 1;
}
else {
// return factorial(6) is (6 * factorial(5)) - return 6 * 5 * 4 * 3 * 2 * 1; return (
$number * factorial(
$number-1);
}
}
// Return a factorial calculation from the factorial() function...$factorial = factorial(6);
echo $factorial;?> // Factorial calculation results:Factorial result:
720
