Ingres II FunctionsПред.
- 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.
