For Loop Challenge Task 2

I don't know what's wrong about the challenge even though I have displayed the correct answer that it ask.

<?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; $i++){
   if($i == isset($facts[$i])){
    echo "<p>$i $facts[$i]</p>\n";
   }else {
    echo "<p>$i</p>";
   }
}
index.php 
<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',

Hi Owa, the problem in your answer is in the isset conditional, you're check if $i is equal to isset and isset return a boolean, so your code is saying something like if ($i == 'true or false') so your code is not running what you want to do, the way to complete this challenge is by checking if the $facts[$i] is set. heres how it should look

<?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; $i++){
  if(isset($facts[$i])){
    echo $i . $facts[$i];
  }else {
    echo $i;
  }
}

hope this can help you, if you have any question, feel free to ask
