MySql tables query

Hi, I need to get an average from a MySql table into another one, using a third table in the middle. As an example, in table A we have the fields A1 A2 and A3. In table B we have the fields B1 A1 B2 (B is the table in the middle) In table C we have the fields C1 B1 C3 I need to get the AVG(A3) into C3. There are more than 1 A record for a C record. This will be a fast job, I need the PHP code for this SQL query to work.
