PHP Arrays and Control Structures: Challenge Task 2 of 2

I have been sitting here for the last half and hour (at least) writing and rewriting this code in all the ways I could. I don't know where I'm going wrong anymore. It tells me that task 1 is no longer passing when I haven't even touched task.) Very confused. Please help.

index.php
<?php
$facts = array(
    57 => ' on Heinz ketchup bottles represents the number of varieties of pickles the company once had.',
    2 => ' is the approximate hours a day Giraffes sleeps',
    18 => ' is the average hours a Python sleeps per day',
    10 => ' per cent of the world is left-handed.',
    11 => ' Empire State Buildings, stacked one on top of the other, would be required to measure the Gulf of Mexico at its deepest point.',
    98 => '% of the atoms in your body are replaced every year',
    69 => ' is the largest number of recorded children born to one woman',
);
//add your loop below this line
for($number=1;$number<=100;$number++) {
  echo $number; 
  if(isset($facts[$number])) {
     echo $facts[$number];
  }
}
}

You have an extra curly brace at the end. Aside from that your code looks good!

Corey is right, extra brace was the error.

I find it helps to comment out the end of conditionals etc like so:

<?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',
);

for ($number = 1; $number <= 100; $number += 1) {
    echo $number;
    if( isset($facts[$number]) ) {
        echo $facts[$number];
    } // endif
} // endfor

I also add vertical space between sections and elements and then spaces after operators. I like to add an extra space between parentheses if there is double or more nested.

I find it all helps to make things more readable; but that's how I do it! :)
