what am I doing wrong ?

I think the control is correct, but i can't understand what is the error on my code.

index.php
<?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 ."\n";

  if(isset($i) == key($facts)){
    echo $facts[$i] ."\n";

  }
}

Hello

Your second if is not correct, you sould first check if $i isset set and then check if the $i key exists in the array, like this

if (isset($i) && array_key_exists($i, $facts)) {
  echo $facts[$i];
}

Hope this helps
