Laravel 集合在嵌套对象上相交

Question

I've two collections given below:

$collection1 = collect([
    [13254, 28.2],
    [13332, 23.45],
]);

$collection2 = collect([
    [14673, 14.2],
    [13254, 12.2],
]);

And I expect the output similar to:

[
    [13254, 28.2],
]

I tried using $collection1->intersect($collection2) but that did not seem to work.

Answer 1

try this code just i use map

$res =  $collectionA->map(function ($item ,$index) use ($collectionB){

        if( (($item[0] == $collectionB[$index][0]) || ($item[1] == $collectionB[$index][1]) ){
            return $item;
        }

    })->filter();
