I have an array that I need to filter for certain things, for example, I might only want records that have the day of the week as Friday. As far as I'm aware this has never worked but it's taking an object and using array_filter on it. Can this work? Is there a better way or a way to do this on with object?

public function filterByDow($object)

{

    $current_dow=5;

    return array_values(array_filter($object, function ($array) use ($current_dow) {

        $array = (array) $array;

            if(!empty($array['day_id']) && $array['day_id'] > -1){

                if($array['day_id'] != $current_dow){

                    return false;

                }

            }

            return true;

    }));

}



$object = $this->filterByDow($object);

Sample data might be like:

$object = (object) array(['id' => '1', 'day_id' => 3], ['id' => '2', 'day_id' => 4]);

As from the comments the array is a laravel collection I guess the answer is:

$filtered = $collection->filter(function ($value, $key) { 

    return $value['day_id'] == 5; 

});

https://laravel.com/docs/5.7/collections#method-filter

try this

    <?php

$items = array(['id' => '1', 'day_id' => 3], ['id' => '2', 'day_id' => 5]);

function filterByDow($items, $dow = 5){

    return array_filter($items, function($item) use ($dow) {

        if($item['day_id'] == $dow){

            return true;

        }

    });



}



$resultArr = filterByDow($items);

print_r($resultArr);

?>

Try to create a collection and implement methods for filtering in it.

class Offer

{

    private $dayId;



    public function getDayId()

    {

        return $this->dayId;

    }



    public function setDayId($dayId)

    {

        return $this->dayId = $dayId;

    }

}



class OfferCollection

{

    const FRIDAY = 5;



    static $dayIds = [

        self::FRIDAY => 'Friday'

    ];



    private $offers = ;



    public function addOffer(Offer $offer)

    {

        $this->offers = $offer;

    }



    public function getOffersByDay($dayId)

    {

        $offers = ;



        if (in_array($dayId, self::$dayIds)) {

            foreach ($this->offers as $offer) {

                if ($offer->getDayId == $dayId) $offers = $offer;

            }

        }



        return $offers;

    }

}
