&reftitle.intro;
The dbx module is a database abstraction layer (db 'X', where 'X'
is a supported database). The dbx functions allow you to access
all supported databases using a single calling convention.
The dbx-functions themselves do not interface directly to the
databases, but interface to the modules that are used to support
these databases.
&reftitle.required;
To be able to use a database with the dbx-module, the module must be either
linked or loaded into PHP, and the database module must be supported by the
dbx-module. Currently, following databases are supported, but others
will follow:
FrontBase (available from PHP 4.1.0).
Microsoft SQL Server
MySQL
ODBC
PostgreSQL
Sybase-CT (available from PHP 4.2.0).
Oracle (oci8) (CVS only).
Documentation for adding additional database support to dbx can be
found at &url.dbx.docs;.
&reftitle.install;
In order to have these functions available, you must compile PHP with
dbx support by using the
option and all options for the databases that will be used, e.g. for
MySQL you must also specify
.
To get other supported databases to work with the dbx-module refer to their
specific documentation.
