PHP PHP Arrays and Control Structures PHP Loops For Looping

I do not see all the facts displayed

I am having a hard time trying to figure out how to get the the matching index from the array to be displayed from the for loop

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++){
  if(isset($facts)){
    echo $i;
  }

}

Hi Gremyko, maybe your should to pass the value of your array like 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++){
  if(isset($facts[$i])) { // here is the little edit you need to see
    echo $facts[$i]; // here is what you need to add
  }
}

Tell if it works for you :)

Thank you, I finally figure it out, I was suppose to leave echo $i; , above the if statement but after the start of the for loop

for($i=1;$i<=100;$i++){

echo $i;

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

echo $facts[$i]; 

} }
