><P
> The MaxDB PHP extension allows you to access the functionality provided by
MaxDB 7.5.0 and above. More information about the MaxDB Database server
can be found at <A

>http://www.mysql.com/products/maxdb/</A

</P
><P
> The MaxDB PHP extension is compatible to the MySQL mysqli extension. There are only
minor differences in the behaviour of some functions due to the differences of the
underlying database servers, MaxDB and MySQL.
</P
><P
> The main differences to mysqli are in the following functions:
