        }
    }
}]

I want to count how many times Network, Body, Display ..., Tests are there in this JSON.

I have tried below code but unable to found exact information regarding the same

$arr1 = above shared json;
$arr1 = json_decode($arr, true);
foreach ($arr1 as $key=>$value){
    $other = $value['other']; //array 
    $counter = 0;
    $lenOther = count($other); //get length of other array
    //reading each element of other array
    foreach($other as $k=>$v){
            $other[$k] = array_count_values($v);
            print_r($other[$k]);
    }

}

Any modification or suggestion of this question would be appreciated.

Apply array_count_values() along with array_column

$arr1 = json_decode($arr, true);

print_r(array_count_values(array_column($arr1[0]['other'],'type')));

Output:- https://3v4l.org/ZHRIa

Note:- If you want to combine all of them based on type and want to create same structure what you have:-

$arr1 = json_decode($arr, true);

$finalArray = array();

foreach($arr1[0]['other'] as $key=>$value){
   $finalArray[$value['type']][] = $value;
}
$newArray = [];
$newArray[] = array('other'=>$finalArray);
print_r($newArray);

Output:- https://3v4l.org/lUrgv

You get the count by using array_count_values method with array_map

just like below

array_count_values(array_map(function($foo) {
    return $foo['type'];
}, $arr['other']));

this will get you the count for each type

you can use foreach with array_key_exists

$jarr = json_decode($json,true);
$r  = [];
foreach($jarr[0]['other'] as $v){
 array_key_exists($v['type'], $r) ? ($r[$v['type']]+=1) : ($r[$v['type']]=1);
}

Working example
