Обсуждение: Connecting PostgreSQL db using Pear
Hi all,
I've been trying to connect to a local PostgreSQL server using Pear, but I
could not succeed:
Here is the connect string:
$dsn = "pgsql://$username:$password@tcp($hostname:$port)/$dbname";
And all the variables seems to be ok when I print $dsn.
However, I get the following error:
"DB Error: connect failed"
What should I do to correct this?
Best regards.

Can you confirm that the postmaster is started with support for TCP
connections? It is possible that in other instances you are connecting
via unix sockets.
I haven't used PEAR myself, but that seems like one possible problem
with the sort of connect string above.
More information might mean others could provide more help.
Cheers,
Andrew.

Good point. Tried this connection parameters in two different servers.
One of them uses Unix domain sockets, the other has a tcp_ip port open...
Anyway, does someone has an example of PostgreSQL + Pear?
Best regards.

Strangely enough, yes. I just did it this week.
// include pear's db stuff
require_once 'DB.php';
// set up your data source
$dsn = "pgsql://vev@localhost/mydatabase";
// connect to your data source
$db = DB::connect($dsn, false);
if (DB::isError($db)) {
die ($db->getMessage());
}
// make your query
$query = "select a from foo";
$res = $db->query($query);
if (DB::isError($res)) {
echo("$query<P>\n");
die ($res->getMessage());
}
// display your results
while ($row = $res->fetchRow())
echo("$row[0]<br>\n");
// disconnect and return
$db->disconnect();
return;
Quite simple actually. I was surprised. The docs make it look
a whole lot harder than it is.
Vince.

No, I still could not succeed...
Here is my pg_hba.conf file:
local all password passwdf
host all 127.0.0.1 255.255.255.255 password passwdf
here is the part of postgresql.conf file:
tcpip_socket = false
#port = 5432
So, what should be the $dsn variable??
Best regards,

Ok, my example assumed you were set up for trust not password. pgsql://username:password@unix+localhost/database_name That *should* do it.

Yes, it did it!
Thanks a lot Vince, you saved a lot of time... Let me now continue coding
my project :)
Best wishes.
