How To convert the Php array to Javascript array

PHP Code:

$input=array(
   array(
       'loc'=>'loc1',
       'lat'=>'32131',
       'lng'=>'23232'
       ),
  array(
       'loc'=>'loc2',
       'lat'=>'111',
       'lng'=>'23232222'
       ),
   
   );
             
$output=array();
foreach($input as $a){
$output[]=array_values($a);

echo json_encode($output); 


Send it to view or whatever and echo as JS variable.
