Laravel - Collections - Method Wherein

The whereIn method removes elements from the collection that do not have a specified item value that is contained within the given array:

    
    $collection = collect([
        ['product' => 'Desk', 'price' => 200],
        ['product' => 'Chair', 'price' => 100],
        ['product' => 'Bookcase', 'price' => 150],
        ['product' => 'Door', 'price' => 100],
    ]);
    
    $filtered = $collection->whereIn('price', [150, 200]);
    
    $filtered->all();
    
    /*
        [
            ['product' => 'Desk', 'price' => 200],
            ['product' => 'Bookcase', 'price' => 150],
        ]
    */
	

The whereIn method uses "loose" comparisons when checking item values, meaning a string with an integer value will be considered equal to an integer of the same value. Use the whereInStrict method to filter using "strict" comparisons.
