Here was their question:
Challenge Task 2 of 2
Use the function isset to test if the incremented value equals one of the keys in the $facts array. If there is a key that matches, display the value AFTER the number.
NOTE: all numbers between 1 and 100 should still be displayed
Bummer! Make sure the fact is displayed directly after the number.
<?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 = 1; $x<=100; $x++) {
if (isset($facts[$x])) {
echo $x." ".$facts[$x]."\n";
} else {
echo $x."\n"; }
}
?>

7,851 PointsThank you. I tried that and it worked. It still seems to me like the first way should have worked also.
