Toto rozšíření je EXPERIMENTÁLNÍ. Chování tohoto rozšíření, názvy funkcí a všechno ostatní, co je zde zdokumentováno, se v budoucích verzích PHP může bez ohlášení změnit. Berte to v úvahu a používejte tento modul na vlastní nebezpečí. |
This module allows to read and write Paradox databases, primary index files and blob files. Write support has been proven to be quite reliable, though due to lack of documentation the produced files may not in any case be readable by other applications. Encrypted databases can be read without specifying a password if pxlib >= 0.5.0 is used.
Poznámka: This module is also in development and may change, though I don't expect major changes to the API.
You need at least PHP 5.0.0 and pxlib >= 0.4.4 for the basic set of functions. Some newer functions are only available with pxlib >= 0.6.0. Reading and writing of encrypted databases requires at least pxlib >= 0.5.0. The paradox library (pxlib) is available at http://pxlib.sourceforge.net.
Informace o instalaci tohoto PECL rozšíření lze najít v kapitole manuálu nazvané Instalace rozšíření PECL. Další informace, jako nové verze, soubory ke stažení, zdrojové soubory, správcovské informace a CHANGELOG, lze najít zde: http://pecl.php.netparadox
Make sure you have pxlib installed before. If you install pxlib from an rpm or debian package, do not forget to install the development package as well.
Toto rozšíření nemá definováno žádné konfigurační direktivy.
The paradox extension provides also an object oriented API. It consists of only one class called paradox_db. 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.

px_new() creates a new Paradox object required by all Paradox functions.
Tyto konstanty jsou definovány tímto rozšířením a budou k dispozici pouze tehdy, bylo-li rozšíření zkompilováno společně s PHP nebo dynamicky zavedeno za běhu.
The following two tables lists all constants defined by the paradox extension.
