XLV. Ingres II Functions
소개
These functions allow you to access Ingres II database servers.
참고: 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).

요구 사항
To compile PHP with Ingres support, you need the Open API library and header files included with Ingres II.
설치
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.
