Merging PHP Arrays for JSON output -

i'm having difficult time trying single array, can return json.

the model:

class coveragelimit extends eloquent {      protected $table = 'webapp_limit_tbl';      public static function index($code,$plan_type,$income_tier){         $data =  coveragelimit::where('limitcode', $code)         ->where('plantypecode', $plan_type)         ->where('incometiercode', $income_tier)         ->get(array('limitcode','limit_desc'));         return print_r($data->toarray());     }  } 

the controller:

$limits = array();     foreach($pieces $coverage_limit) {     $limits = array_merge($limits, coveragelimit::index($coverage_limit,$plan_type,$income_tier)); //this works suggestion below     }  return $limits; 

returns:

array (     [0] => array         (             [limitcode] => l0001             [limit_desc] => $1m per claim / $2m annual aggregate         )  ) array (     [0] => array         (             [limitcode] => l0002             [limit_desc] => $2m per claim/ $2m annual aggregate         )  ) [true,true] 

the goal output following json data via json_encode($limits):

[{"limitcode":"l0001","limit_desc":"$1m per claim / $2m annual aggregate"},{"limitcode":"l0002","limit_desc":"$2m per claim / $2m annual aggregate"}]

i think need single array below in order accomplish this, can't seem make happen.

array (     [0] => array         (             [limitcode] => l0001             [limit_desc] => $1m per claim / $2m annual aggregate         ),     [1] => array         (             [limitcode] => l0002             [limit_desc] => $2m per claim/ $2m annual aggregate         )  ) 

i grateful on how merge return single array valid json output. or if there way return foreach 1 array. thanks.

first, not use return print_r($data->toarray());

that incorrect. return $data->toarray() , should work fine.

the problem print_r returns boolean , outputs stdout text representation of data structure. why see annoying [true, true] @ end of output example. array attempting json_encode array 2 values of true returned print_r.
