Why is this code wrong? @@

First set $i = 1, then while $i <= 100, determine if $facts[$i] exists, if so, echo the corresponding value string. if $facts[$i] does not exists, just print the $i.

I've lost here, why is the code not correct? Many thanks in advance :)

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[$i]) {
    echo "$i" . $facts[$i] . "<br />\n";
  } else {
    echo "$i" . "<br />\n";
  }
};

?>

<?php
for ($i = 1; $i <= 100; $i++) {
  if (isset($facts[$i]) {//how many opening paranthesis, and how many closing paranthesis, should you have
    echo "$i" . $facts[$i] . "<br />\n";
  } else {
    echo "$i" . "<br />\n";
  }
};

Doh! Yes you are absolutely right Antonio De Rose, Dave varmutant. Funny how obvious it is now after you have pointed that out. Before that, I spent an hour staring at my code line by line and didn't have a clue! xD

Thank you guys & bless! :)
