Stuck on for loop code challenge

I have been working on this challenge for a while. I can get the first question, but once I start adding the isset function, everything goes off the rails. I just can't figure out how to do this and get all of the numbers and the values from the array in the output.

Any hel p is appreciated. Thanks.

index.php 
<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
    2 => ' is the approximate hours a day Giraffes sleeps',
    18 => ' is the average hours a Python sleeps per day',
    10 => ' per cent of the world is left-handed.',
    11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
    98 => '% of the atoms in your body are replaced every year',
    69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for ($x = 0; ++$x <=100 || isset($facts[57]) = $x);) {
  echo $x , "<br/>\n";
}

You shouldn't be doing isset in the for loop, if you read the php manual the examples show the isset used in an IF statement. Keep the for loop the same as task one but you need to add in an IF statement to test where the array is Null. My code for example:

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

I thought it was something like that, but I wasn't sure. Thanks so much.
