PHP比较2个数组并在匹配时添加字段

Question

I have arrays dishesand favorites. My goals is to add a field to the dishes array if a certain dish occurs in the favoritesone. This is what I have tried but it doesn't seem to be working since I get an empty array back.

$boundDishes = [];

foreach ($dishes as $dish) {
    foreach ($favorites as $favorite) {
        if ($favorite == $dish) {
            $dishes['favorite'] = true;
            $boundDishes[] = $dish;
        }
    }
}
return $boundDishes;

Am I doing something wrong or is there a better way?

Any help is very much appreciated!

Many thanks in advance!!

Answer 1

To make this an answer, you are returning $boundGames but not adding anything to it so that's why it's empty, did you mean to add to $boundGames instead of $boundDishes in your loop as below?

$boundGames = [];

foreach($dishes as $dish) {
    foreach($favorites as $favorite) {
        if($favorite == $dish) {
            $dishes['favorite'] = true;
            $boundGames[] = $dishes;
        }
    }
}
return $boundGames;

Alternatively, did you mean to return $boundDishes?
