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, the following databases are supported, but others will follow:
FrontBase (available from PHP 4.1.0).
Sybase-CT (available from PHP 4.2.0).
Oracle (oci8) (available from PHP 4.3.0).
SQLite (CVS only).
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.
Správanie tejto funkcie je ovplyvnené nastaveniami v php.ini.
For further details and definition of the PHP_INI_* constants see ini_set().
Poznámka: This ini-option is available available from PHP 4.3.0.
Tu je krátke vysvetlenie konfiguračných direktív.
Columns names can be returned "unchanged" or converted to "uppercase" or "lowercase". This directive can be overridden with a flag to dbx_query().
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 holds the result of a query.
Konštanty uvedené nižšie sú definované týmto rozšírením a budú dostupné iba keď rozšírenie bolo buď kompilované do PHP alebo dynamicky načítané za behu (runtime).
