scala - Recommended style for arity-1 call followed by arity-0 call -

-

given official scala style guide
http://docs.scala-lang.org/style/method-invocation.html
recommends using infix notation arity-1 calls , dot notation arity-0 calls, what's recommended style arity-1 call followed arity-0 call?

for example, recommended way?

(bytes map (_.tochar)).mkstring

the summary of style guide basically: use point-free style whenever simple , clear. otherwise, don't. in case, options are

bytes.map(_.tochar).mkstring (bytes map (_.tochar)).mkstring

and former looks simpler , clearer me, wins.

really long chains not clear in point-free notation

foo bar baz qux quux bippy

say again?

foo.bar(baz).qux(quux).bippy

oh, okay.

be pragmatic. point-free style can clean , elegant. coding style lead write code looks nice point-free. point of syntax clear , avoid errors, use whichever better accomplishes goal.

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 $row): ?> <div id="<?=$...
