Installation

Contents

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 Ingres

<IfModule mod_env.c>
    PassEnv II_SYSTEM
    PassEnv LD_LIBRARY_PATH
</IfModule>

Note:
For example configurations for different web servers and operating systems see » http://community.ingres.com/wiki/Ingres_Articles#Ingres_and_Web_Servers.
