Php group array of object

Question

I mentioned my php array object following below,

$arr ='[
{
    "id": 4667,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "255",
    "height": "35",
    "rim": "19",
},
{
    "id": 4668,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "275",
    "height": "35",
    "rim": "19",
},
{
    "id": 4669,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "255",
    "height": "35",
    "rim": "19",
},
{
    "id": 4670,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "275",
    "height": "35",
    "rim": "19",
}]';

I want to split array into front and rear separate like following below based on width.

$front = '[
{
    "id": 4667,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "255",
    "height": "35",
    "rim": "19",
},
{
    "id": 4669,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "255",
    "height": "35",
    "rim": "19",
}]';

$rear = '[
{
    "id": 4668,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "275",
    "height": "35",
    "rim": "19",
},
{
    "id": 4670,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "275",
    "height": "35",
    "rim": "19",
}]';

It's there any way php can compare each object width value and group them which is match. please advise. thanks for your valuable time.

code is not valid it should be like: $arr='[{ "id": 4667, "brand": "Michelin", "model": "Pilot Super Sport", "width": "255", "height": "35", "rim": "19" }, { "id": 4668, "brand": "Michelin", "model": "Pilot Super Sport", "width": "275", "height": "35", "rim": "19" }, { "id": 4669, "brand": "Pirelli", "model": "Zero", "width": "255", "height": "35", "rim": "19" }, { "id": 4670, "brand": "Pirelli", "model": "Zero", "width": "275", "height": "35", "rim": "19" }]'; — PHP Hupp Technologies, Oct 27 '21 at 11:22

I think you can use below code:

$arr='[{
    "id": 4667,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "255",
    "height": "35",
    "rim": "19"
}, {
    "id": 4668,
    "brand": "Michelin",
    "model": "Pilot Super Sport",
    "width": "275",
    "height": "35",
    "rim": "19"
}, {
    "id": 4669,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "255",
    "height": "35",
    "rim": "19"
}, {
    "id": 4670,
    "brand": "Pirelli",
    "model": "Zero",
    "width": "275",
    "height": "35",
    "rim": "19"
}]'; 
$front=[];
$rear=[];
foreach(json_decode($arr,true) as $key=>$val)
{
  
  if($val['width']==255)
  {
    $front[]=$val;
  }
  else{
    $rear[]=$val;
  }
}  

$front=json_encode($front);
$rear=json_encode($rear);

Thanks for your replay i need to split array based on width – Haja Oct 27 '21 at 11:16
You can pass argument based on width in array_chunk. – PHP Hupp Technologies Oct 27 '21 at 11:17
if total elemets are 10 then you need 5 in front and 5 in rear, right? – PHP Hupp Technologies Oct 27 '21 at 11:19
Sometime we will get available product 3 front tires & 5 rear tires, in database return all 8 elements in single array i need to display product front and rear separate, we can identify front and rear using width only – Haja Oct 27 '21 at 11:23
I have updated code please check. you can put condition for front as per requirement. – PHP Hupp Technologies Oct 27 '21 at 11:39
Thanks for your effort, but i am sorry thats not working for me. in following link they did that using javascript i need to do something like that in php. ref: https://stackoverflow.com/questions/46794232/group-objects-by-multiple-properties-in-array-then-sum-up-their-values – Haja Oct 27 '21 at 11:49
Did you correct your JSON? it should be like:$arr='[{ "id": 4667, "brand": "Michelin", "model": "Pilot Super Sport", "width": "255", "height": "35", "rim": "19" }, { "id": 4668, "brand": "Michelin", "model": "Pilot Super Sport", "width": "275", "height": "35", "rim": "19" }, { "id": 4669, "brand": "Pirelli", "model": "Zero", "width": "255", "height": "35", "rim": "19" }, { "id": 4670, "brand": "Pirelli", "model": "Zero", "width": "275", "height": "35", "rim": "19" }]'; – PHP Hupp Technologies Oct 27 '21 at 11:55
For front what are the width we need to consider or its fixed 255? – PHP Hupp Technologies Oct 27 '21 at 11:55
Yes i update corrections, thank you so much.. & 255 is not fixed value it will change based on tire modal but every JSON will have only two different width size – Haja Oct 27 '21 at 12:01
Yeah so you need to make dynamic check here if($val['width']==255) as per your requirement – PHP Hupp Technologies Oct 27 '21 at 12:02
Sorry for late reply, PHP Hupp Technologies.. Yeah ive got spark after look into your code and finally i get what i need.. please check if there's any way to make that code optimize please advise – Haja Oct 27 '21 at 12:19
$all = []; $front = []; $rear = []; for($i=0; $iwidth); } $filter = array_unique($all); $max = max($filter); $min = min($filter); for($j=0; $jwidth == $max){ array_push($rear, $arr[$j]); } else if($arr[$j]->width == $min){ array_push($front, $arr[$j]); } else { echo 'Not Match'; } } echo ""; echo ""; – Haja Oct 27 '21 at 12:20

This is works for me but need to simplify

 $all = []; $front = []; $rear = [];

        for($i=0; $i<count($arr); $i++){
            array_push($all, $arr[$i]->width);
        }

        $filter = array_unique($all);
        $max = max($filter);
        $min = min($filter);
        
        for($j=0; $j<count($arr); $j++){
            if($arr[$j]->width == $max){
                array_push($rear, $arr[$j]);
            } else if($arr[$j]->width == $min){
                array_push($front, $arr[$j]);
            } else {
                echo 'Not Match';
            }
        }

        echo "<script>console.log(".json_encode($front).")</script>";
        echo "<script>console.log(".json_encode($rear).")</script>";
