[UPHPU] returning MySQL

[Timothy Humphrey]

How would one return the "auto increment" number from a newly created 
record automatically?

For example:
<?
$record = "INSERT INTO database VALUES ('', '$var_1','$var_2', '1', 
'$var_3')";
		$result = $db->query($record);
		$db->commit();
?>

I would want to create another variable for the auto increment number 
that the database assigned to that new entry.

Hope that makes since.
