There are several levels of messages from PHP.  This one is a warning, not an
error, but your installation of PHP is showing warnings.

You can get around it by defining the variable at the top of your program:

$myvariable = 0;

or 

$myvariable = "";

When you redefine the value from your SQL statement, it will replace the value
given to the variable initially.
