@version V4.65 22 July 2005 (c) 2000-2005 John Lim (jlim#natsoft.com.my). All rights reserved.

|

Released under both BSD license and Lesser GPL library license. You can choose which license
|
||
you prefer.
|
||
|
||
PHP's database access functions are not standardised. This creates a need for a database
|
||
class library to hide the differences between the different database API's (encapsulate
|
||
the differences) so we can easily switch databases.
|
||
|
||
We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, DB2,
|
||
Informix, PostgreSQL, FrontBase, Interbase (Firebird and Borland variants), Foxpro, Access,
|
||
ADO, SAP DB, SQLite and ODBC. We have had successful reports of connecting to Progress and
|
||
other databases via ODBC.
