c# - Is it necessary to await a single asynchronous call -

-

this question has answer here:

if i'm returning result of single asynchronous function e.g. in service between application layers, there difference between:

    public task<byte[]> getinsurancepolicydocument(string itineraryreference)     {         return this.coreitinerarydocumentservice.getinsurancepolicydocument(itineraryreference);     }

and:

    public async task<byte[]> getinsurancepolicydocument(string itineraryreference)     {         return await this.coreitinerarydocumentservice.getinsurancepolicydocument(itineraryreference);     }

there few subtle differences in cases - example, if original task returns status of faulted operationcanceledexception async version return task status of canceled... unless need of subtlety, better go first code , avoid (very slight) overhead of wrapping it.

php - render data via PDO::FETCH_FUNC vs loop -

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
