php - MySQL group duplicates together

I have a MYSQL database which looks like this:

 ID      | Name    | Product
 --------+---------+----------
 65644   | Charlie | Beer
 65644   | John    | Beer
 65644   | Jan     | Beer
 65644   | Phoebe  | Beer

 65644   | Shaun   | Beer

I would like to output a table using php to look something like this:

 ID      |               Name                | Product
 --------+-----------------------------------+----------
 65644   | Charlie, John, Jan, Phoebe, Shaun | Beer

Currently I've only been able to output it to look like this first table. Any help would be greatly appreciated.
