6,999 Pointsi dont get how i should display the value with the corresponding key if the isset() function is true.
if someone could provide me with the right code for this exercise, it would be awesome. im just stuck for to long and getting mad :P tnx!
<?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 \n";
}
if(isset($i)){
echo ??????????;
}

Treehouse TeacherHi there! You did great setting up your for loop so I'm going to give some hints here and see if you can get it accomplished.
- Your
if
statement should be inside yourfor
loop - The newline character in the first echo statement is not needed and will cause the challenge to fail
- If
$facts
at an index of$i
is set (isset
) then echo out the value at that index - Make sure the value at the $facts[$i] is echoed out without any spacing or the challenge will fail
Hope this helps, but let me know if you're still stuck!

6,999 Pointsi was able to solve it! i had to solution to display the facts all along but i thought it didnt work. but my if statement was not inside my for loop.
