I'm getting the correct input, But this is telling me it's not. Please help :)

what am I missing?

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 $i . "<br/>\n";
    if ((isset($i)==true)&&$i==57) {
    echo $facts[57];
}
}

Hi Carlos, I'm not sure what you're doing with $facts[57], the newline concatenation is also something that the 'mysterious answer checking engine' seems to dislike too, so I just removed the two things. What you end up with is the answer :)

<?php
for ($i = 1; $i <= 100; $i++) {
    echo $i;
    if (isset($facts[$i]) == true) {
        echo $facts[$i];
    }
}

Because isset() returns true or false, you can shorten the conditional check:

<?php
for ($i = 1; $i <= 100; $i++) {
    echo $i;
    if (isset($facts[$i])) {
        echo $facts[$i];
    }
}
