PHP FizzBuzz

fizzbuzz.php

<?php

$x = 100;

for ( $i = 1; $i <= $x; $i++ )
{

  if ( ( $i % 5 == 0 ) && ( $i % 3 == 0 ) )
  {
    echo "fizzbuzz\n";
  }
  elseif ( $i % 5 == 0 )
  {
    echo "fizz\n";
  }
  elseif ( $i % 3 == 0 )
  {
    echo "buzz\n";
  }
  else
  {
    echo $i."\n";
  }

}

?>

The $x variable isn't needed. You can just go with $i <= 100 in the for statement.
