Illegal offset type error in PHP

Alright, I'm a little lost. Here's my code, but how do I get rid of the PHP error that tells me it's an illegal offset type? I'm trying to cycle through the colors.

$color = array(

    [0]=>"red", 
    [1]=>"cherry",
    [2]=>"orange",
    [3]=>"amber",
    [4]=>"blue",
    [5]=>"sapphire",
    [6]=>"green",
    [7]=>"forest green",
    [8]=>"purple",
    [9]=>"lavender");
 //starts at index 0

for($colorCount=0; $colorCount <=9; $colorCount++){

    if ($colorCount == 9){
        break;
    }
    echo implode(", ", $color).", ";

}

$color = array(

        '0'=>"red", 
        '1'=>"cherry",
        '2'=>"orange",
        '3'=>"amber",
        '4'=>"blue",
        '5'=>"sapphire",
        '6'=>"green",
        '7'=>"forest green",
        '8'=>"purple",
        '9'=>"lavender"
        );
foreach ($color as $key => $res) {
       print_r($res);
}

I think what might be happening is that, since PHP now supports short-array notation with []. It's parsing [0] as array(0) which you then try to use as a key in an array, which is not allowed. This would explain that exact error message.

Declare your array like:

$color = array(
    0 => "red", 
    1 => "cherry",
    2 => "orange",
    3 => "amber",
    4 => "blue",
    5 => "sapphire",
    6 => "green",
    7 => "forest green",
    8 => "purple",
    9 => "lavender"
);

You can even leave off the numbers and do:

$color = array(
    "red", 
    "cherry",
    "orange",
    "amber",
    "blue",
    "sapphire",
    "green",
    "forest green",
    "purple",
    "lavender"
);
