i'm still stuck. i tried what the last gentleman suggested and it still isn't working
<?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; $i++) {
echo "$count[$i] . \n";
} if (isset $facts[$count] = $i {
echo " " . $facts[$i] . "<br />\n";
}
?>

28,694 Pointsthe following seems to pass:
<?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}"; // I probably should have used $i or "$i". no need for more complex {} binding
if(isset($facts[$i])) {
echo $facts[$i];
}
echo "<br />\n";
}
It just moves the test on being set inside the loop (reflected by indentation).

Courses Plus Student 31,764 PointsThis is the way (<br> tags not required, just for formatting):
//add your loop below this line
for($i=1;$i<=100;$i++) {
echo $i.'<br>';
if(isset($facts[$i])) {
echo $facts[$i].'<br>';
}
}

28,694 Points(1) you seem to be referring to a variable called $count. I'm guessing you meant $i. (2) isset is a function so needs to be of form isset($valueToTest). It returns a Boolean so can be used directly in a conditional statement. (3) Also I think you confused '==' with '='. '==' is a test, while '=' attempts assignment. This will either break the code if assignment is illegal, or make things unpredictable.
