<?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; $i++) {
if (isset($facts[$i])) {
echo $i . $facts[$i] . "\n";
} else {
echo $i . "\n";
}
}
