system tables postgreSQL with php

[Anon]

Hi!

I'm working with php 4.0.6 for an application with a postgreSQL database.

I must find the columns names for all tables, and all tables in this database.

A similar application I've maked a few days ago with Solid database.
In this "old" application I've used Unified ODBC functions like odbc_column (), odbc_primarykey(), ...

Now can I get all tables and others similar informations from system tables or functions?

Thanks!

Cristian!
