                //  print_r($var1);
                    
                    foreach($var1 as $id){
                    
                        
                        $encode_data = $id['id'] . $id['channel'][0].  $id['id'] .  $id['channel'][1];
                        
                        $see = json_encode($encode_data);
                
                    
                    }
                    
                    print_r($see);
                    
                    print_r($encode_data);
                    //
                    die;
                    $info['user_hash'] = $encode_data;

You should be clear in your post. But given the information, I assume you need to change the array you have to that JSON.

What you have:

$databaseArray = [[ "id" => "e4da3b7fbbce2345d7772b0674a318d5", "channel" => [1,2]]];
$json = json_encode($databaseArray);

What you want:

$databaseArray = [[ "id" => "e4da3b7fbbce2345d7772b0674a318d5", "channel" => 1]];
$json = json_encode($databaseArray);

What you need to change:

$databaseArray = [
    [ "id" => "e4da3b7fbbce2345d7772b0674a318d5", "channel" => [1,2]],
    [ "id" => "1235437fbbce2345d7772b0674a32342", "channel" => [1,2]]
];
$databaseMergedArray = [];
     // You need to set the channel to a value instead of array. 
     foreach($databaseArray as $key => $item) {
         foreach($databaseArray[$key]["channel"] as $channel) {
             $item["channel"] = $channel;
             $databaseMergedArray[] = $item;
         }
     }

$json = json_encode($databaseMergedArray);
echo ($json);
