[Database class] Questions and Answers

[Paul S. Wang]

Dear DB Class,

Q.  What value do I use to insert into an AUTO_INCREMENT column?

A.  NULL

Q.  When I execute the php require($file) statement a second time,
    I got an error.  Why?

A.  It is an error to include/require any php file in your php program
    more than once.   To avoid such a mistake,  use require_once($file).
