Php group array of object-CodePudding

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.

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);

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>";
