Thread: Help Conecting to a database from PHP

Hi All!

My PC has Slackware Linux 9.1 installed.

And Apache and PHP are working well....I can make and use the PHP functions in my web pages. Recently I've downloaded
andinstalled PostgreSQL 7.3.2, it seems to work well too, I can make databases, tables and all...But when I try to use
thePHP functions to connect to the database (pg_connect or pg_pconnect) it doesn't work. I've granted select permission
tomy user and nobody user in the table of the databse, and my pg_hba.conf seems to be ok (  localhost        all    all
  trust ). 
The browser even not give any error or something....it just don't work...

I think I'm using the function in the correct way: $conn = pg_connect ("localhost","","","","mydbname");

I've tried too: $conn = pg_connect ("dbname=mydbname");

with and without the port number (5432), and when I type: netstat -nat       it shows:

    0.0.0.0:5432      LISTEN

in the list

I'm starting the database server in this way: /usr/local/pgsql/bin/postmaster -i -D /usr/local/pgsql/data

thanks....

does somebody know what can I do?

Maybe some error messages are in logfiles? Where are log files for yout
postgresql and for your web server?

I suppose you have used wrong format. The line in pg_hba.conf should read:
host all all 127.0.0.1 255.255.255.255 trust

> I think I'm using the function in the correct way: $conn = pg_connect
> ("localhost","","","","mydbname");

If I remember correctly this form has been deprecated...

I suppose you may safely drop listening on TCP/IP connections. "local"
connections should be fine.
In that case insert a line into pg_hba.conf:
local all all trust
(...if you want to do it in fast but extremely unsecure way.)

Connecting from PHP you may try to use explicit username, hovewer I think your
problem is in this pg_hba.conf's line with localhost.
Even if your hba_conf is OK, have you enabled "tcpip_socket" in
postgresql.conf?

Maybe there are conflicts with versions of modules used by PHP and your
postgres? Have you had an older version of PostgreSQL before? Have you
recompiled PHP, apache? Just guessing...
