php - Sum of a field which stored as an array and group by the same id in laravel 4 -


i have field in table called "images" stored array, 

$new_item_photos = item::wherein('id', [10, 15, 10])->get();         foreach ($new_item_photos $new_photos) {             if ($new_photos->id == $new_photos->id) {                 $total_photos += count($new_photos->images);             } else {                 $total_photos = count($new_photos->images);             }              echo $total_photos."<br>";         }

i result 

id photos 10 8 15 9 10 7

now want sum $total_photos , filter duplicate id loop, ex:

id photos 10 15 15 9

can please me on this?

ps: images saved in array format in table

you can use array store count of photos each id. modified example helps further

$new_photos = item::wherein('id', [10, 15, 10])->get(); $total_photos=[];  foreach ($new_photos_dealers $new_photos_dealer) {     if ($new_photos->id == $new_photos->id) {     if(array_key_exists($new_photos->id,$total_photos)) {             $total_photos[$new_photos->id] += count($new_photos->images);     } else {             $total_photos[$new_photos->id] = count($new_photos->images);     {         $total_photos[$new_photos->id] += count($new_photos->images);     } else {         $total_photos[$new_photos->id] = count($new_photos->images);     }      echo print_r($total_photos, true)."<br>"; }

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
