PHP：检查另一个数组中是否存在数组值

Question

i have created a array like this :

$foods_customer = array(["meal"=>1,"rice"=>1];

when i return this array , looks like :

[{meal: 1, rice: 1}]
0: {meal: 1, rice: 1}
meal: 1
rice: 1

and i have another array like this :

$foods , when i return , looks like this .

[{meal: 1}, {meal: 1, rice: 1}]
0: {meal: 1}
meal: 1
1: {meal: 1, rice: 1}
meal: 1
rice: 1

i wanna check if array $foods_customer , exist inside array $foods.

in this case , must return true , bit if $foods_customer was like this :

[{meal: 1, rice: 1 , chesse:1}]
    0: {meal: 1, rice: 1,chesse:1}
    meal: 1
    rice: 1
    chesse:1

so , return false .

You can do it very easily with just foreach and Identical checking. First make a loop of your main array then make another loop inside of it and then check the array identically.

Try this out:

$foods_customer = array(["meal"=>1,"rice"=>1]);
$foods  = array(["meal"=>1 ],["meal"=>1,"rice"=>1]);

$res = false;
foreach( $foods as $food ){
    foreach( $foods_customer as $fc ){
        if( $fc === $food ){
            $res  = true;
            break;
        }
    }
}

echo $res;
