Courses Plus Student 14,543 PointsChallenge Task 2 of 2. Arrays and Control Structures within FOR loops
Totally lost here Team. How do I display the value after the number?
<?php
$facts = array(
57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
2 => ' is the approximate hours a day Giraffes sleeps',
18 => ' is the average hours a Python sleeps per day',
10 => ' per cent of the world is left-handed.',
11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
98 => '% of the atoms in your body are replaced every year',
69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for ($i =1; $i<= 100; ++$i) {
echo $i . "<br />\n";
if (isset($facts)) {
echo $facts;
}
}

Hi there Dave!
Hope i can help you out here :) as i just did this like 1 hour ago.
so this is how i did it :
for($i=1; $i <= 100; $i++){
echo $i;
if(isset($facts[$i])){
echo $facts[$i];
}
echo "\n";
}
Explanation (step by step but your issue is at the bottom )=>
remember that $i is referring to the " key" in the associative array? 1.>> so all you are doing is displaying all numbers from 1 to 100 2.>> Then you are checking IF it just so happens to be TRUE that any of the numbers looped through when increasing $i (the number that is going up) also "coincidentally" ;) correlate with any of the Keys ( $facts[$i]) in the array $facts. 3.>> IF what i referred to above is true then... you are only displaying the actual fact which you refer to by echoing $facts[$i]. 4.>> Lastly you are adding a line break regardless of whether the conditional was true or false.
cheers
