Can't pass this challenge. Why?

Use the function isset to test if the incremented value equals one of the keys in the $facts array. If there is a key that matches, display the value after the number

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; $i++){
  if (isset($facts[$i])) {
       echo $i . " " . $facts[$i]. "<br/>";
    }
}

For the challenge you specified, it says that you need to add onto your previous code.

You are on the right track, and in my opinion your code would make more sense but they want it in a different manner.

You final code should look something like this (They didn't want you to surround the echo $i with the if statement)

<?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;

  if (isset($facts[$i]))
  {
    echo $facts[$i];
  }
}
?>
