PostgreSQL version: psql (PostgreSQ
Operating system: Linux
Description: DB Error: connect failed ... PHP/PostgreSql
Details:
hi...
I am working on PHP using postgreSQl as DB...
Both r very new to me....
i logged in as root and
created a user root
the command i hav used : createuser root
and
database sample : createdb sample
then to check list of database i used command : psql -l
the RESULT was
List of databases
Name | Owner | Encoding
-----------+----------+----------
sample | root | UNICODE
template0 | postgres | UNICODE
template1 | postgres | UNICODE
(3 rows)
then i created a table in DB sample name "login"
using normal sql query and inserted two datas
i created file "show.php" to display the content on web page
the code is as follows :-
<?php
include("DB.php");
$username = "root";
$password = "";
$hostname = "localhost";
$dbname = "sample";
$dsn = "pgsql://$username:$password@$hostname/$dbname";
echo "The DSN : $dsn<br>";
$con = DB::connect($dsn);
echo "The Connection Object : $con<br>";
if(DB::isError($con))
{
$valu = DB::isError($con);
echo "Error Number : $valu <br>";
$val1 = $con->getMessage($valu);
echo "The Message : $val1<br>";
}
else
{
echo "Connection established <br>";
}
$sql="SELECT id,name FROM login";
echo "$sql<br>";
echo "$rs = $con->query($sql);";
echo "$rs<br>";
if(DB::isError($rs))
{
die($rs->getMessage());
}
while($row = $rs->fetchRow(DB_FETCHMODE_ASSOC))
{
$fulid = $row['id']." ";
$fulname = $row['name']." ";
echo "Details : $fulid $fulname<br>";
}
$con->disconnect();
?>
i created a directory name example in /var/www/html
and saved show.php there....
when i am executing this file as
http://localhost/example/show.php
its displaying :
The DSN : pgsql://root:@localhost/sample
The Connection Object : Object id #2
Error Number : 1
The Message : DB Error: connect failed
SQL QUERY : SELECT id,name FROM login
i hav tried a lot to find out the error but unable to find it

PHP/PostgreSql This is probably *not* a bug in PostgreSQL, and you'll be able to find better help at the pgsql-general/pgsql-novice/pgsql-php mailing lists.

Are you logging connection attempts on the server-side and what does it show? 2. Have you tried turning error verbosity up? 3. What does "psql -U root -h localhost sample" do for you? 4. Have you checked your pg_hba.conf file It's almost certainly an issue with #4 - the pg_hba.conf file. -- Richard Huxton Archonet Ltd
I fail to see how this is a bug, but...
Are you running the webserver as root? Most systems don't do that
(for good reason!). You should turn on log_connections and
log_disconnections in postgresql.conf and see what it shows is
happening (you might need to turn up log_min_messages).
