so can access id results parsing json response "id" field.

note returned json array of results , not single definitive answer. need work out correct 1 (order not guaranteed either not assume first entry likely).

also worth noting though documented returning 'id' , integer value, current preferred usage of ids supply 'id_str' , string representation of integer. due inconsistencies in how various platforms handle , limit integers. if receive 'id' should use 'id_str' future interactions.

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