Blocked by the objective again. Please help me.

I got a feeling how the solution should be look like, but I can't make it right. I guess it's because I didn't see enough code in my life. Please show me the answer so I can think of it.

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 $i;
  for (isset ($i);$i=57){
    echo $fact[$i];
};

Hi Amy,

The challenge asks you to use a conditional inside your for loop to determine if your loop variable is present in the array keys. We can test for the conditional with an "if" statement. You need to replace your second "for" statement with an "if" statement that checks if $i is present in the array keys. That would like like this

if (isset (array[key])) {
}

Hope this helps.
