PHP PHP Arrays and Control Structures PHP Loops For Looping

Need help displaying 1-100 with FOR loop on PHP.

Not sure what I'm doing wrong with this challenge task. When I go to preview my code I get the numbers it's asking for. Probably another formatting issue.

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 ($facts = 1; $facts <= 100; $facts++) {
    echo $facts;
}
?>

You shouldn't call the variable in the for loop facts because you need the facts variable in a later task just rename "facts" i in the for loop to "i" so it stands for integer.

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

Thanks
