Hi!, and a Question

Hello to everybody!

I'm David from Colombia.

I'm learning Postgresql and using PHP. And I'm trying
to connect from my php web page to PostgreSQL, I use
this function:

$connection = pg_connect("host=gatuno port=5432
dbname=cdtaller4_3");

and when I look it on the browser it shows:

Fatal error: Call to undefined function: pg_connect()
in /var/www/index2.php on line 8

- I have PostgreSQL 7.4 , Apache is working well, and
all other php scripts too. I'm using knoppix and I
looked at the KPackage and I have php4-pgsql
installed.

Does somebody know what could be happening?

thanks!

You have not got pgsql support compiled into PHP.

Either PHP has not been compiled into PHP, or the extension has not been
turned on. Look in php.ini for a line looking like:

;extension=pgsql.so

and uncomment it (remove the ;) so it looks like:

extension=pgsql.so

Re: Hi!, and a Question

Hi!, about this, I'm using it local, in the same
server is postgresql and the database and the apache
web server too. I have downloaded the php-pgsql again
and install it again, it was an rpm and i have knoppix
(debian), so I did it with #alien -i, I have this in
my php.ini

extension=pgsql.so

------

I have pgsql.so in /usr/lib/php4/20020429 which is the
place where phpinfo(); says it's searching for
extensions


-------
and my /etc/postgresql/pg_hba.conf says:

#
# TYPE DATABASE USER IP-ADDRESS
IP-MASK METHOD
# Database administrative login by UNIX sockets
local all all
trust
#
# All other connections by UNIX sockets
local all all
trust
#
# All IPv4 connections from localhost
host all all 127.0.0.1
255.255.255.0 trust
#
# All IPv6 localhost connections
host all all ::1
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff trust
host all all ::ffff:127.0.0.1/128
trust
#
# reject all other connection attempts
localhost all all 192.168.1.6
255.255.255.0 trust

-------
and the phpinfo page shows:

pgsql
PostgreSQL Support enabled
Active Persistent Links 0
Active Links 0

Directive Local Value Master Value
pgsql.allow_persistent On On
pgsql.auto_reset_persistent Off Off
pgsql.max_links Unlimited Unlimited
pgsql.max_persistent Unlimited Unlimited

-----
I don't know what am I doing but it doesn't work, when
I execute the php web page:







$db = pg_connect("dbname=cdtaller4_3");
$query = "select * from empleados";
$result = pg_exec($db, $query);
if (!$result) {
printf ("ERROR");
$errormessage = pg_errormessage($db);
echo $errormessage;
exit;
}
?>





It doesn't shows any error or something it stays on
the same page it was, and do nothing...

Thanks...if somebody knows another configuration I'm
forgetting.. (PHP 4, Apache, PostgreSQL 7.4.2, Knoppix
3.4)

thanks!

Re: Hi!, and a Question

Check your apache log to see if error messages are being logged there.
I'll make a guess anyway. With a connect statement like:
$db = pg_connect("dbname=cdtaller4_3");
You should also have user=xxxxx inside the quotes.
You may or may not have more success by adding host=localhost.
