输出一个字符串来描述数组中的颜色和新数量？

Question

I have a question about this code that I'm trying to figure out, as I am new to PHP. Here is the code:

$fruit_counts=array('apple'=>3, 'banana'=>4, 'orange'=>0);
$fruit_colors=array('apple'=>'red', 'banana'=>'yellow', 'orange'=>'orange', 'plum'=>'purple');

How do I output a string describing the color and new amount (count) of each fruit? Any help would be much appreciated. Thank you.

Since it seems like all fruits will have a color, but not necessarily a quantity, just loop through the colors and see if there is a quantity for the corresponding fruit:

$fruit_counts = array('apple' => 3, 'banana' => 4, 'orange' => 0);
$fruit_colors = array('apple' => 'red', 'banana' => 'yellow', 'orange' => 'orange', 'plum' => 'purple');

foreach ($fruit_colors as $fruit => $color) {
    $qty = isset($fruit_counts[$fruit]) ? $fruit_counts[$fruit] : 0;
    echo "Fruit: $fruit  |  Color: $color  |  Qty: $qty" . '<br>';
}
