Similar to .net attributes in Go -

-

what similar .net attributes in go lang.

or how achieved ?

perhaps similar mechanism struct tags. not elegant, can evaluated @ runtime , provide metadata on struct members.

from reflect package documentation: type structtag

they used, example, in json , xml encoding custom element names.

for example, using standard json package, have struct field don't want appear in json, field want appear if not empty, , third 1 want refer different name struct's internal name. here's how specify tags:

type foo struct {     bar string `json:"-"` //will not appear in json serialization @     baz string `json:",omitempty"` //will appear in json if not empty     gaz string `json:"fuzz"` //will appear name fuzz, not gaz }

i'm using document , validate parameters in rest api calls, among other uses.

if keep 'optionally space-separated key:"value"' syntax, can use method of structtag access values of individual keys, in example.

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