Hi all me again. Any ideas why I keep getting a 'Bummer: I do not see all numbers from 1 to 100' message ?

<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
    2 => ' is the approximate hours a day Giraffes sleeps',
    18 => ' is the average hours a Python sleeps per day',
    10 => ' per cent of the world is left-handed.',
    11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
    98 => '% of the atoms in your body are replaced every year',
    69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for($i = 1; $i <= 100; $i++) {
  echo $i;
  foreach($facts as $key => $value){
      if(isset($facts[$key]) == $i){    
          echo $i;
          echo $value;
      }
    }
  }
 ?>
