for loop task 2 problem

Question

I've used for each loop to pass all the key instead of for loop. what is the problem here.

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 />";
}

foreach($facts as $key => $value){
  if(isset($key)){
    echo "$key : $value <br />";
  }
}

I solved it this way...

for ($i = 1; $i <= 100; $i++){
    if (isset($facts[$i])){
        echo "$i";
        echo $facts[$i] . "<br />";
  } else {
  echo "$i <br />";
}
}
