isset

Help me out it's very confusing

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 $i;
  if(isset($facts) == $i)
    echo $facts[$i]; 
}

Hi Ayish,

You are almost there, for the first part you need only to echo $i from 1 to 100. And in the second part you need to check if current for cicle item exist if it exist it should be echoed according to task. So it would be something like that.

// It checks if current element in array exist at index $i
if(isset($facts[$i])) {
   // If it's true then echoed out
   echo $facts[$i];
}

I hope it helps:)
