PHP Array Issue [duplicate]

Question

I have two array Array1 and Array2 and want to get related data from these arrays. let me elaborate further.

Array1

Array
(
    [42] => 1
)

Array2

Array
(
    [42] => 30215
    [43] => 15478
)

Now i want to something like this.

 Array
    (
        [42] => 30215
    )

Since in your first array your keys are not the values you don't have to flip it and just take the: array_intersect_key() of both arrays — Rizier123

Here array_intersect_keys will returns an associative array containing all the entries of array1 which have keys that are present in all arguments. and max will find the highest value of those

$arr1 = Array
(
    '42' => 1
);
$arr2 = Array
(
    '42' => 30215,
    '43' => 15478
);
echo max(array_intersect_key($arr2, $arr1));//30215
