Can somebody help me with this?

<?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"; };

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

The comment section always telling me that the number 1 requirement is not passing I dont seem to get what is the problem?

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."\n";
};

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

Hi,

I got it to pass by using one for loop which displays each number 1 to 100 but then the corresponding fact if it exists:

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