This » PECL extension is not bundled with
PHP. Information for installing this PECL extension may be found in
the manual chapter titled Installation of PECL extensions. Additional information
such as new releases, downloads, source files, maintainer
information, and a CHANGELOG, can be located here: » https://pecl.php.net/package/ingres.
You can download the DLL for this PECL extension
from » http://esd.ingres.com/product/drivers/PHP/.
To have these functions available, you must
» download and compile this
extension, enabling Ingres support using the –with-ingres[=DIR] option, where DIR
is the Ingres base directory. If the II_SYSTEM environment
variable is not set correctly you may need to use –with-ingres=DIR to specify your
Ingres installation directory.
PHP code written for version 2.x and later is not
backward-compatible with earlier versions of this PHP extension.
However, it is possible to run two incompatible releases within the
same PHP environment using the –enable-ingres2 option. This
configuration option renames the extension to ingres2, changing
function names, configuration settings, and constants. For example,
with this option enabled, ingres_connect() becomes ingres2_connect().
To use this extension the system environment
variable II_SYSTEM must be defined. Linux and UNIX users will also
need to define the shared library search path, for example,
LD_LIBRARY_PATH. When used with the Apache
web server these variables must be set explicitly in the startup
script for Apache. In addition, the PassEnv directive is
required for the Ingres extension to load the correct shared
libraries. For example:
Example #1 Example usage of PassEnv for
<IfModule mod_env.c> PassEnv II_SYSTEM PassEnv LD_LIBRARY_PATH </IfModule>
For example configurations for different web
servers and operating systems see » http://community.ingres.com/wiki/Ingres_Articles#Ingres_and_Web_Servers.
