Please give an example of how the display should look like

not sure how exactly the display should look like.

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',
);

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

}
?>

Hi there, Pratibha Menon! I feel like you have a great understanding of what the output should look like and your logic is spot on! You do, however, have a small syntax error and you are simply missing a closing parenthesis.

You wrote this:

 if(isset($facts[$i]){

But take a good look at that. There´s two opening parentheses (, but only one closing parentheses. You should have the same number of closed parentheses as you do open parentheses.

You meant to write:

 if(isset($facts[$i])){  // note the additional ")" before the open curly brace

When I make that one teensy change, your code passes with flying colors! Good job! :sparkles:
