I did not understand this Challenge. Please someone help clarify !

` <?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[$i])){ echo "$key $value"; } } } ?> `

index.php

The challenge wants you to do a for loop that prints the numbers 1 - 100 (including 100)

So for the time being, remove your foreach loop, use print rather than echo, and you might want to add 1 to your for loops terminating condition.

you're printing the wrong outcomes, here is the answer;

for($i = 1; $i <= 100; $i++){
  print $i ;
  if(isset($facts[$i])){
    print $facts[$i]; 
  }

}
