Something wrong with PHP - facebook like count :     <?php 
    function fbLikeCount($id,$access_token){
      //Request URL
    	$retrievedID == 1633003770266238; // dynamic variable from another field $output["id"];
      $json_url ='https://graph.facebook.com/'.$id.'?fields=fan_count&access_token='.$access_token;
      $json = file_get_contents($json_url);
      $json_output = json_decode($json);
      //Extract the likes count from the JSON object
      if($json_output->fan_count){
      return $likes = $json_output->fan_count;
      }else{
      return 0;
      }
    }
    echo fbLikeCount($retrievedID,'288268074855652|b36552b96683cbcfa794b4f6185e6daa');
    
    
    ?>

This code has been working since I want to use $retrievedID as a dynamic and get the value from other variable.. Now the count is not showing at all and gets the error. Please help
