PHP PHP Arrays and Control Structures PHP Loops For Looping

I'm not sure what I did wrong here. Please help

I checked the isset documentation. im drawing a blank..

$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;

 bool (isset($i == [$facts])){
    echo $facts;

to pass the challenge the loop will need to be displayed as so:

for($i = 1; $i <= 100; $i++){
    echo $i;
         echo $facts[$i];

The problem is that the keys of the array are in a different range. I suggest updating the keys and the solution looks like this.

$factsWithNewKeys = array_values($facts);

for ($i = 0; $i < count($factsWithNewKeys); $i++) {
