I found this post randomly googling some PHP issue and thought I would put my spin on it. I consider myself a below entry level programmer, it’s a hobby that I hope to someday turn into a job. Anyway, here’s my convoluted solution.

$c = “Fizz”; $d = “Buzz”; $e = “n”;

for($i=1;$i<=100;$i++){ $a = $i%3; $b = $i%5; if(!$a){ if(!$b){ echo $c.$d.$e; }else{ echo $c.$e; } }elseif(!$b){ echo $d.$e; }else{ echo $i.$e; } }

Wow Jyrki that certainly is a very umm compact answer :P

How about 75 bytes? Geeky enough? :)

for($i=1;$i<101;$i++)echo $i%15?$i%5?$i%3?$i:’Fizz’:'Buzz’:'FizzBuzz’,”\n”;

I really liked this but,

for ($num=1; $num<=100; $num++) { if ($num%3 == 0) { echo "Fizz"; $keepNum = true; } if ($num%5 == 0) { echo "Buzz"; $keepNum = true; } if (!$keepNum) { echo $num; } $keepNum = false;

    echo "<br />";

}

I really like yours Ken, I cleaned it up a bit ;-)

foreach (range(1,100) as $num) { $msg =''; if ($num%3 == 0) $msg = "Fizz"; if ($num%5 == 0) $msg .= "Buzz"; if (!$msg) $msg = $num; print "$msg\n"; }

Heh, noticed you changed the conditional in the main article now.

I like how the conditional doesn’t print Buzz, even though that’s a requirement.

wouldn’t this work better:

foreach (range(1,100) as $number) { $msg=”; if ( $number%3 == 0) { $msg .= “Fizz”; } if ($number%5 == 0) { $msg .= “Buzz”; } if (empty($msg)) { $msg = $number; } print “$msg\n”; }

Of course, being the conditional lover I am, I would probably write the last if (the empty check) to this:

foreach (range(1,100) as $number) { $msg=”; if ( $number%3 == 0) { $msg .= “Fizz”; } if ($number%5 == 0) { $msg .= “Buzz”; } printf (”%s\n”, (empty($msg) ? $number : $msg)); }

Well, the second approach is overkill really, and uses extra processing power. The first and last examples are the most efficient really when it comes to readability and processing.
