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.
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 (soon, I hope :-):
Documentation for adding additional database support to dbx can be
found at http://www.guidance.nl/php/dbx/doc/.
In order to have these functions available, you must compile PHP with
dbx support by using the --enable-dbx
option and all options for the databases that will be used, e.g. for
MySQL you must also specify
--with-mysql=[DIR].
To get other supported databases to work with the dbx-module refer to their
specific documentation.
Esta extensión no define ninguna directiva de configuración.
There are two resource types used in the dbx module. The first one is the
link-object for a database connection, the second a
result-object which helds the result of a query.
Estas constantes están definidas por esta extensión y
estarán disponibles solamente cuando la extensión ha sido
o bien compilada dentro de PHP o grabada dinamicamente en
tiempo de ejecución.
