php - Merge three mysql entries to one entry -

I have 3 or 4 entries with different entries than a person with the same name.

  ABC ---- ---- ----------- A 01 XXX A 02 XYZ A 03 ABC   
 How can I merge them by choosing them which is always in a way similar to A in the structure:  
  ABCDEF --- --- --- --- --- - 01 02 03 XXX XYZ ABC   
 Hope you can help me get it.

 If there is a variable number of entries for different users then use the GROUP_CONCAT function. This is a simple way to create a dynamic number of columns in SQL (some processing in php).  
  SELECT A, GROUP_CONCAT (B) B, GROUP_CONCAT (C) C from table group A;   
 The result will be: - ABC --- --- --- 01,02,03 XXX, XYZ, ABC  
 It can be further processed in php code.
