Can't get passed Task 2 of this challenge

Why isn't this working?

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

Hi Scott,

In your code you are printing the number twice if the array contains it. Remove the print of the $i variable inside the if statement, as the task wants you to print the sentence not the number again.

Actually the $i you're referring to is supposed to be there. I just had to restructure the if/else.
