XLV. Ingres II Functions
Introduction
These functions allow you to access Ingres II database servers.
Note: 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).
Warning
This extension is EXPERIMENTAL. The behaviour of this extension
-- including the names of its functions and anything else
documented about this extension -- may change without notice
in a future release of PHP. Use this extension at your own
risk.
Requirements
To compile PHP with Ingres support, you need the Open API
library and header files included with Ingres II.
Installation
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.
