For loop - PHP

Mission: "Create a FOR loop that displays each number from 1 to 100. Make sure that you DO NOT show 0 and you DO show 100."

Result: "Bummer! Make sure you end with 100"

What is wrong with the code below?

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

Hey Ufuk, Your for loop is actually set up correctly, but your echo statement isn't right. The question is asking to just output the numbers 1 to 100, so all you have to do is:

for ($i = 1; $i <= 100; $i++) {
  echo $i;
}

Make sense? Hope this helps!
