LX. Ingres II Functions
These functions allow you to access Ingres II database servers.
Замечание:
If you already used PHP extensions to access other database
servers, note that Ingres doesn't allow concurrent queries and/or
transaction over one connection, thus you won't find any result
or transaction handle in this extension. The result of a query
must be treated before sending another query, and a transaction
must be committed or rolled back before opening another
transaction (which is automatically done when sending the first
query).
To compile PHP with Ingres support, you need the Open API library
and header files included with Ingres II.
Это расширение PECL
не поставляется вместе с PHP.
Дополнительная информация, такая как новый версии,
скачивание, исходные файлы, информация о разработчике и CHANGELOG, могут
быть найдены здесь:
http://pecl.php.net/package/ingres.
In order to have these functions available, you must compile PHP with
Ingres support by using the
--with-ingres[=DIR] option, where DIR is
the Ingres base directory, which defaults to /II/ingres.
If the II_SYSTEM environment variable isn't correctly set you may have to
use --with-ingres=DIR
to specify your Ingres installation directory.
When using this extension with Apache, if Apache does not start
and complains with "PHP Fatal error: Unable to start ingres_ii
module in Unknown on line 0" then make sure the environment
variable II_SYSTEM is correctly set. Adding "export
II_SYSTEM="/home/ingres/II" in the script that starts Apache, just
before launching httpd, should be fine.
Поведение этих функций зависит от установок в php.ini.
