How to prevent duplicate IDS in foreach statement PHP

I am doing a foreach that stores data to a datebase. The only problem am having is with the generated IDS. Each added item into database should have it's own unique fileID.

   foreach ($videos['items'] as $videoResult) {
     **$musicThis = Music::Where('file', '=', $videoResult['id']->videoId)->get();**
     if(count($musicThis) < 1) {
     $music_id = substr(md5(time()+$videoResult['snippet']['title']), 0, 11);
     $music = new Music;
     $music->filename = $videoResult['snippet']['title'];
     $music->fileDesc = $videoResult['snippet']['description'];
     **$music->fileID = $music_id;**
     $music->save();
     }
    }

When this is executed, my database ends up with the same fileID, which is not what I want. How can I do this right?

Simpler test case:

var_dump(1+"foo", 1+"bar");

Warning: A non-numeric value encountered
Warning: A non-numeric value encountered
int(1)
int(1)

You may want to concatenate rather than sum.

In any case, the overall logic is pretty confusing. time() has a 1-second resolution so it'll sometimes clash on duplicate titles, some times not.
