Oops! It looks like Task 1 is no longer passing.

I keep getting this useless message that task 1 is not passing. How to fix this?

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])){
        $tmp = $i+1;
        echo $tmp."\n";
        }
}
?>

Hi Ketan Singh,

Well you don't need two for loops, one is enaugh. It should look something like this.

<?php
for($i = 1; $i <= 100; $i++) {
  // Just echoing numbers from 1 to 100
  echo $i;
  // If there is a key that matches, display the value AFTER the number
  if(isset($facts[$i])) {
    echo $facts[$i];
  }
  // Added this line to read better in "Preview" Tab
  echo "<br>";
}
?>
