php - how to find a specific objet in a liste of object (other way than a loop) -

-

i know if possible retrieve object list through id (or other way). far have loop , test each object see if correct one.

exemple
here exemple retrieve dbb liste of object picture (this list pictures).

step_1 => determining best picture id depending on attribut scorelike. highest scorelike picture best picture)

step_2 => want set attribut bestpicture yes picture id equal value of variable $id_of_best_picture, otherwise should set no.

    // step_1 - determining best picture id     // ----------------------------------------     $bestscorelike = o;     foreach($pictures $picture)     {       $scorelike = $picture->getscorelike();       if($scorelike > $bestscorelike)       {         $bestscorelike = $scorelike;         $id_of_bestpicture = $picture->getid();       }     }      // step_2 - having loop find object again     // ------------------------------------------------------     foreach($pictures $picture)     {       if($picture->getid() == $id_of_bestpicture)       {         $picture->setbestpicture('yes');       }       else       {         $picture->setbestpicture('no');       }     }

if want set "yes" 1 of picture pictures array, should use code this;

$bestscorelike = 0; $bestpictureobject = null; foreach($pictures $picture) {     $scorelike = $picture->getscorelike();     if($scorelike > $bestscorelike)     {         /**          * in $bestpictureobject exists picture scorelike less current $picture          */         if (!is_null($bestpictureobject)) {             $bestpictureobject->setbestpicture('no');         }         $bestscorelike = $picture->getscorelike();         $bestpictureobject = $picture;     } else {         $picture->setbestpicture('no');     } } $bestpictureobject->setbestpicture('yes');

you can create list keys equals $object->id , have access $pictures[$best_picture_id].

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
