      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).

  安装此 PECL 扩展库的信息可在手册中标题为 <A
HREF="install.pecl.html"
>PECL 扩展库安装</A
>的一章中找到。 更多信息如新版本，下载，源文件，维护者信息以及更新日志等可以在这里找到：

TARGET="_top"
>http://pecl.php.net/package/ingres</A
>.
 </P
><P
>&#13;  In order to have these functions available, you must compile PHP with
  Ingres support by using the
  <CODE
CLASS="option"
>--with-ingres[=DIR]</CODE
> option, where DIR is
  the Ingres base directory, which defaults to <TT
CLASS="filename"
>/II/ingres</TT
>.
  If the II_SYSTEM environment variable isn't correctly set you may have to
  use <CODE
CLASS="option"
>--with-ingres=DIR</CODE
>
  to specify your Ingres installation directory.
 </P
><P
>&#13;  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.
