LXVII. Unified ODBC functions
In addition to normal ODBC support, the Unified ODBC functions in PHP allow you to access
several databases that have borrowed the semantics of the ODBC API to implement their own API.
Instead of maintaining multiple database drivers that were all nearly identical, these drivers have
been unified into a single set of ODBC functions.
The following databases are supported by the Unified ODBC functions: Adabas D, IBM DB2, iODBC, Solid, and Sybase SQL Anywhere.
Note: There is no ODBC involved when connecting to the above databases. The functions
that you use to speak natively to them just happen to share the same names and syntax as the ODBC
functions. The exception to this is iODBC. Building PHP with iODBC support enables you to use any
ODBC-compliant drivers with your PHP applications. iODBC is maintained by
OpenLink Software. More information on iODBC,
as well as a HOWTO, is available at
www.iodbc.org.
