Front End Web Development Techdegree Graduate 20,818 PointsI'm not sure what I did wrong here. Please help
I checked the isset documentation. im drawing a blank..
<?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 $i;
bool (isset($i == [$facts])){
echo $facts;
}
}

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

11,600 PointsThe problem is that the keys of the array are in a different range. I suggest updating the keys and the solution looks like this.
$factsWithNewKeys = array_values($facts);
for ($i = 0; $i < count($factsWithNewKeys); $i++) {
echo($factsWithNewKeys[$i]);
}
