I really don't get what I'm doing wrong

It says "I don't see a key named 'mike' " In my mind it's clearly there. I don't understand whats wrong.

index.php 
<?php

//Place your code below this comment
$integer_one = 1; 

$integer_two = 2;

$golden = 1.618;

$bool = TRUE;

$colors = array('red','blue','green');

echo $colors[1];

$favorite_colors = array('mike','jane','chris');

$mike = 'green';

$jane = 'blue';

$chris = 'yellow';



?>

It is asking you to add "Associative Array" and what you are writing is an "Indexed Array"

You should do this:

<?php

//Place your code below this comment
$integer_one = 1; 

$integer_two = 2;

$golden = 1.618;

$bool = TRUE;

$colors = array('red','blue','green');

echo $colors[1];

$favorite_colors = array('mike'=>'green','jane'=>'blue','chris'=>'yellow');

?>

Hey Kyle!! You have to do an associative array at the end. What you did wrong is that you are creating new variables and adding the colors string to each one. You are supposed to make the $favorite_colors array in a 'key' and 'value' assignment. Here is how I completed the challenge so you can check more in detail how you are supposed to make an associative array.

<?php

//Place your code below this comment
$integer_one = 1;
$integer_two = 2;

$golden = 1.618;
$bool = true;
$colors = array('red','blue','green');


echo $colors[1];

// associative array: $example =  array('key' => 'value')

$favorite_colors = array('mike' =>'green',
                         'jane'=>'blue',
                         'chris'=>'yellow');
