Thread: PHP/PostGreSQL Articles
Hello ;) I manage a small albeit promising website (not for profit, no ads, no subscriptions) dedicated to PHP Programming (http://www.dotgeek.org) We (I) are looking for writers on the following topics: -Articles with examples of PHP and postgresql development - Migration from Mysql to Postgresql I might be willing to pay for good articles, (payment per article or on a deal basis). The budget is modest but it could fit well if you are a student and have some spare time handy. It could be something fun and interesting at the same time. Feel free to msg email me at geeks at dotgeek dot org for any further information, Regards David Costa
Hi this php code:
// add to DB
// database access parameters
$host = "localhost";
$user = "postgres";
$pass = "postgres";
$db = "cosc3p94";
// open a connection to the database server
$connection = pg_connect("host=$host dbname=$db user=$user
password=$pass");
if (!$connection)
{
die("Could not open connection to database server");
}
...
results in:
Could not open connection to database server
and I'm not sure why. The web browser, web server, and database are on
the same machine..
I checked the pg_hba.conf and it says this:
# TYPE DATABASE USER IP-ADDRESS IP-MASK
METHOD
local all all
trust
# IPv4-style local connections:
host all all 127.0.0.1 255.255.255.255
trust
# IPv6-style local connections:
host all all ::1
ffff:ffff:ffff:ffff:ffff:ffff:ff$
which is untouched from the default settings...

OK, here's a little trick you may not be aware of.
pg_connect("dbname=mydb user=stan");
will open a local unix domain socket.
pg_connect("host=127.0.0.1 dbname=mydb user=stan");
will open a local TCP/IP connection on the loopback interface.
In order for this to work, your postgresql.conf must have this line
changed:
#tcpip_socket = false
to
tcpip_socket = true
and your pg_hba.conf needs a line like this:
host all all 127.0.0.1 255.0.0.0 trust
So it's likely the "secure by default" mentality of postgresql that's
biting you here.
Hello,
What does the PostgreSQL log say? Is it even getting to the server? What
abour the apache error log? Does it reflect an error?
Sincerely,
Joshua D. Drake

yes, this was the problem, thanks... On 12-Feb-04, at 10:30 AM, scott.marlowe wrote: > > In order for this to work, your postgresql.conf must have this line > changed: > #tcpip_socket = false > to > tcpip_socket = true
Hi David-
Although you'll find the PHP experts on this list, you may have more luck
finding authors on the advocacy list. I'll cc the advocacy list on this
response. I'm pretty sure that migration from MySQL to PostgreSQL will be a
popular topic in that group.
