The wonderful if Statements

Helpful tip:

It is now considered best practice to use the '===' operator unless you have specific reason to use the '==' operator.
Google that and Yoda Conditions if you want to develop good habits that follow Official Symfony Best Practices from the start. Yoda Conditions help you catch an accidental assignment operator (=) on what should of been a comparison operator (=== or ==)

Hello,
I tried to rewrite code from challenge 3 to make it work.
But for some reason 'Website' think that "Frisbee" is "Tennis ball" and echo 'color' "Yellow" although it schould echo 'color' "surprise".

 <?php
$contents = file_get_contents('toys.json');
$toys = json_decode($contents, true);
?>

<?php foreach ($toys as $toy) { ?>
<h3><?php echo $toy['name']; ?></h3>
<h4>
    <?php
    if ((array_key_exists('color', $toy)) && ($toy['name'] = 'Tennis Ball')) {
        echo 'Yellow';
    } elseif (array_key_exists('color', $toy) && $toy['name'] = 'Frisbee') {
        echo 'surprise';        
    } else{
        echo 'no color';
    }
    ?>
</h4>
<?php } ?>
