This module allows to read Paradox database and primary index files. It
has initial support for creating Paradox databases. Consider it to be
experimental due to lack of documentation of the Paradox file format.
Nota:
This module has not been tested on other platforms than Debian/GNU Linux
for PPC.
Nota:
This module is also in development and may change, though I don't expect
major changes to the API.
A short installation note: just type
in your console.
Esta extensión no tiene directivas de
configuración en php.ini.
The paradox extension provides also an object oriented API. It consists of
only one class called paradox_doc. Its methods only differ from the
functions in its name and of course the missing first parameter. The
following table will list all methods and its equivalent functions.
Tabla 1. Methods of class paradox_doc
Estas constantes están
definidas por esta extensión y estarán disponibles
solamente cuando la extensión ha sido o bien compilada dentro
de PHP o grabada dinámicamente en tiempo de ejecución.
