Введение

This module provides an additional session save handler for the session module using PostgreSQLPostgreSQL as a storage system. A user session save handler may be used ((session_set_save_handler(), but this module is written in C. Therefore, this module could be twice as fast, compared to a session save handler written in PHP.

Session PgSQL is designed to scale any size of web sites and offers some advanced features:

Требования

You need at least PHP >= 4.3.0, and PostgreSQL >=7.2.0 as database server. libpq that comes with PostgreSQL 7.2.0 or later (and header files to build) and libmm (and header files).

Установка

Short installation note:

• Untar the tar.gz archive into php4/ext (Latest official releases can be found at SourceForge PHP Form Extension Project)

• If the new directory is now called something like session_pgsql. You should name it to session_pgsql (except you only want to build it as self-contained php-module).

• Run ./buildconf in php4

• Run configure --with-session-pgsql (and your other options)

• make; make install

Настройка во время выполнения

Поведение этих функций зависит от установок в php.ini.

PostgreSQL session save handler is still under development. Refer to the README file in the source distribution for configuration details.

Table definitions

I have at the moment not very much time to further develop this extension. I will implement more and more features in the near future.
