PHP for loop

I have some trouble passing this chalenge, this is my current code, I am not sure what i am missing here...

for ($i = 0 ; $i <= 100; ++$i) { if(isset($i,$facts)) { print $facts; } }

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

Hey,

Well, since we have an array, you'll want to access the array elements, I'm not going to modify your for statement.. (which runs 100 times when there is only a few elements in the array)

<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
    2 => ' is the approximate hours a day Giraffes sleeps',
    18 => ' is the average hours a Python sleeps per day',
    10 => ' per cent of the world is left-handed.',
    11 => ' Empire State Buildings, stacked one on top of the other, would be d to measure the Gulf of Mexico at its deepest point.',
    98 => '% of the atoms in your body are replaced every year',
    69 => ' is the largest number of recorded children born to one woman',
);
for ($i = 0 ; $i <= 100; ++$i) { 
    if(isset($facts[$i])) { 
        print $i . $facts[$i] . "\n";
    } 
}

Also you'll want to print the index as it's used in the sentence

Why do we use "$i" instead of "$facts?" Is it the default variable for all "for" loops?

In Fact you not read the question well you must create your own loop start from 1 not zero ,, the challenge want you to echo from 1 to 100 not zero to 100

<?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] . "\n";
    }
}
