how to check if once go to if block never go to else block

I'm developing webservice. In Request categories id are like,

$categories_string = 1,2,3,4,5.

In response i have to return json array with whole data (from 3-4 tables) associated with all ids. so i use explode() function for string to array. so after this code my array is,

$category_id_array = explode(',',$categories_string );

So , i got array in $category_id_array.

So Problem is that if there is a data in single categories i have to give response even if there is no data in other categories.

Current Output : From this code if there is data in 3 categories among 4 categories it will give (data of 3 and for 4th one there is no data so it will go to else block) So is there a way to check if once go to if block never go to else block or any other logic for this functionality.

Expected Output : Functionality is that among 4 categories if there is data in one categories and not in other categories it show only first categories data if data is in 2 categories it will give data of 2 categories vice versa.

Note : I have to use else block here (if there is no data in all categories than it must respond with else block)

So for that i use below code.

          foreach ($category_id_array as $single_cat_value) {
                        $res_whole_criteria = $this->db->query("SELECT * , ( 3959 * ACOS( COS( RADIANS(  '$latitude' ) ) * COS( RADIANS( latitude ) ) * COS( RADIANS( longitude ) - RADIANS(  '$longitude' ) ) + SIN( RADIANS(  '$latitude' ) ) * SIN( RADIANS( latitude ) ) ) ) AS distance, information_business.name AS business_name FROM information_business LEFT JOIN category ON information_business.category_id = category.id LEFT JOIN offers ON offers.category_id = category.id WHERE category.id =  '$single_cat_value' HAVING distance < 10 ORDER BY distance");

                        $row_whole_criteria = $res_whole_criteria->result();
                        echo "<pre>";
                        print_r($row_whole_criteria);
                        $business_id = $row_whole_criteria['0']->business_id;

                        // code for count business_wise_like starts here 

                        $like_count_businesswise = $this->db->query("SELECT COUNT( id ) AS business_wise_like FROM  `business_likes` WHERE business_id = '$business_id'");
                        $row_like_businesswise = $like_count_businesswise->result();
                        $businesswisecount = $row_like_businesswise['0']->business_wise_like;

                        // code for count business_wise_like ends here 

                        if($res_whole_criteria -> num_rows > 0)
                        {
                                $response['success'] = "1";
                                $response['message'] = "List found for near by Business Data";
                                $response["data"] = array();
                                $counter = 0;
                                foreach($row_whole_criteria as $row)
                                {
                                        $data = array();
