javascript - Iterate over sockets in socket.io v1? "...has no method 'clients'" -

-

before able write this:

io.sockets.clients().foreach(function (socket) {      socket.emit(signal,data); });

now, cannot , error object #<namespace> has no method 'clients'

is there way this? socket v1.0. (or 1.0.2 think).

for know can use io.emit(), iterate on sockets , perform functions on them in timer. can refactor callbacks , set timer on io.on(), think need able use references (i think javascript make copy of object socket in case instead of referencing it?)

here's example

setinterval(function(){     io.sockets.clients().foreach(function (socket) {          socket.emit('newmessage',somecalculations());     }); },1000);

if info connected sockets has send single socket 

    (var in io.sockets.connected) {         var s = io.sockets.connected[i];         if (socket.id === s.id) {            continue;         }         socket.emit('notify_user_state', s.notify_user_state_data)     }

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