How to check if JSON object is empty in PHP?

Question

I\'m reading JSON data with PHP and that data contains empty objects (like {}). So the problem is, I have to handle the case when object is empty in different m

Answer 1

I am not sure if this is more or less effective than casting to an array but I would guess more. You could just start to loop the object and as soon as you find something you have an answer and stop looping.

function is_obj_empty($obj){
   if( is_null($obj) ){
      return true;
   }
   foreach( $obj as $key => $val ){
      return false;
   }
   return true;
}
