First of all modify your query like this to get the id of category

select filter_categories.id,filter_categories.filter_category,
filter_tags.filter_tag from filter_categories JOIN filter_tags ON 
(filter_tags.filter_category_id=filter_categories.id) where   
 filter_categories.filter_id='".$_GET["id"].

then suppose your result are coming into $arrfilterALLDetails array then just use the for loop to modify the result as want above like below.

 $arrfilterDetails = array();
 foreach ($arrfilterALLDetails as $key => $value) {
          $arrfilterDetails[$value['id']]['filter_category'] = $value['filter_category'];
          $arrfilterDetails[$value['id']][$value['filter_tag']] = $value['filter_tag'];
        }
print_r($arrfilterDetails);

Just play with this a littlebit you will get the result as you want.
