Must the isset function be nested inside the forloop and how?

Must the isset function be nested inside the forloop and how?

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;

this is the proper answer.

<?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++){
  print $i;
  if(isset($facts[$i])){
    print $facts[$i]; 
  }

Yes, it needs to be inside the for loop as you need to check if the $facts array has a key corresponding to the $i variable and echo it, if it does, so it also needs to be after the echo $i; line too.
