These functions allow you to access Ingres II database servers.
</para>
<note>
<para>
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 commited or rolled back before opening another
transaction (which is automaticaly done when sending the first
query).

<para>
To compile PHP with Ingres support, you need the Open API library
and header files included with Ingres II.
</para>

<section id="ingres.installation">
&reftitle.install;
<para>
In order to have these functions available, you must compile php
with Ingres support by using the
<link linkend="install.configure.with-ingres">--with-ingres</link> option.
If the II_SYSTEM environment variable isn't correctly
set you may have to use
<link linkend="install.configure.with-ingres">--with-ingres=DIR</link>
to specify your Ingres installation directory.
</para>
<para>
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 environement
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.
