Where is the problem - For loop - Challenge Task 2 of 2

Question

Use the function isset to test if the incremented value equals one of the keys in the $facts array. If there is a key that matches, display the value after the number.

My solution:

<?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 ( $i = 1 ; $i <=100; $i++){ if ( isset($facts[$i]) ){ echo "$facts[$i] \n"; }; };

?>

Hey Bade,

You basically completed the challenge, except for missing one of the instructions, so great work :D

The second step asks:

"Use the function isset to test if the incremented value equals one of the keys in the $facts array. If there is a key that matches, display the value after the number."

Which means it expects you to display the value of the key if it's found in the array, which you've done. However, it also asks that you display the value -after the number-, which is a reference to the echo statement created in the first step.

You've removed the echo statement in your code, which is causing it to fail.

Using your provided code, and following that missed direction, the following code will 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;

  if (isset($facts[$i])) {

    echo "$facts[$i] \n";

  };

};

Good luck with the course!
