I have absolutely no idea how to approach Challenge Task 2 of 2. Please can somebody tell me what I need to do?
<?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;
}

You've done everything right up to this point. Now you should check if one of the incremented values is one of the keys in the $facts array. In your for loop you have to check with an if statement whether the value is set (isset).
if (isset($facts[$i]))
If a "key" matches, you give the value after the number.
{
echo "$facts[$i]";
}
Best regards - phil

15,028 PointsThank you, Philipp! I think that makes sense... Some of these concepts seem illogical to me at first and quite difficult to grasp.
