php - Multi row toJSON function using Propel and Backbone -

i'm trying make should simple "list all" function using propel orm - backbone.js read. want do, , in opinion, should work:

$users = usersquery::create() ->find();  echo $users->tojson(); 

however, when i'm running that, results i'm getting are:

{"users_0":{"id":1,"emailaddress":"sdf","password":"sdf","createdat":null,"modifiedat":null}, "users_1":{"id":2,"emailaddress":"dsf","password":"sdf","createdat":null,"modifiedat":null}} 

whilst it's valid json, fact ever row array in main array throwing off json. need return json this:

[{"id":1,"emailaddress":"sdf","password":"sdf","createdat":null,"modifiedat":null},{"id":2,"emailaddress":"dsf","password":"sdf","createdat":null,"modifiedat":null}] 

i've created below function (as test) , works perfectly, surely propel (or slim, framework i'm using) has way of stopping being inside array? here hack;

$users = usersquery::create() ->find();  $json = '['; foreach($users $user){     $json = $json.$user->exportto('json').','; } $json = $json.']'; echo str_replace("},]", "}]", $json); 

any appreciated! all.

i hate it, think 1 of "that's how propel works" situations. said, improve helper function little more robust.

i put code in userquery class:

class usersquery extends baseusersquery {   ...    public function tojsonarray() {     $users = $this->find();     $userarray = array();     foreach($users $user){       array_push($userarray, $user->toarray());     }     return json_encode($userarray);   } } 

and use so...

$userjson = usersquery::create()->tojsonarray(); 

or if have other criteria...

$userjson = usersquery::create()               ->filterbysomefield("somevalue")               // other criteria ...               ->tojsonarray();
