Question

I can currently query the join of two tables on the equality of a foreign/primary key in the following way.

 $result = mysql_query(\"SELECT * FROM `table1` 
         


        

Answer 1

SELECT * 
FROM table1 
INNER JOIN table2
      ON table1.primaryKey=table2.table1Id
INNER JOIN table3
      ON table1.primaryKey=table3.table1Id
