I have removed comma from last value of aray by using last key of array. Hope this will give you idea.

   $last_key =  end(array_keys($myArray));
                           foreach ($myArray as $key => $value ) {
                              $product_cateogry_details="SELECT * FROM `product_cateogry` WHERE `admin_id`='$admin_id' AND `id` = '$value'";
                                  $product_cateogry_details_query=mysqli_query($con,$product_cateogry_details);
                                  $detail=mysqli_fetch_array($product_cateogry_details_query);

                                  if ($last_key == $key) {
                                    echo $detail['product_cateogry'];
                                  }else{
                                    echo $detail['product_cateogry']." , ";
                                  }

                          }
