Re: Problems in connecting to postgreSQL using PHP

["Kitty Yuen" <kitty3a@xxxxxxxxx>]

Dear Valentín,

I think I have already enabled the extension and found the extension in my pgsql.ini file in php.d folder. However, I still cannot connect to the database. I guess I have something to be config in the PostgreSQL. Do you have any ideas?

OK. Now you have to activate the library to connect PHP to PostgreSQL, this is in the php.ini file. In Windows 2000 it is in the following folders: C:\WINNT and in the PHP installation folder, in my case: C:\AppServ\php. Once you find this file you have to discomment this extension: extension=php_pgsql.dll, to do that you are going to erase the ";" at the beggining of the line.

Look for this file (php.ini) in your O.S. and configured it. If you are using Linux I guess it is in the etc/profile/php.config directory, but I0m not sure.

I'm attaching you my file:

Here are my error messages from PHP:

Could you provide any PHP errors or the pg_hba.conf ?
