Re: Problems in connecting to postgreSQL using PHP

Here are my error messages from PHP:


[Mon Mar 12 16:01:26 2007] [error] [client 127.0.0.1] PHP Warning:
pg_connect()
[<a href='function.pg-connect'>function.pg-connect</a>]: Unable to connect

the server running locally and accepting\n\tconnections on Unix domain
socket &quot;/tmp/.s.PGSQL.5432&quot;? in /var/www/html/try.php on line 3

PHP Code:


<?php

// Connecting, selecting database

$dbconn = pg_connect("dbname=test user=postgres")

   or die('Could not connect: ' . pg_last_error());



// Performing SQL query

$query = 'SELECT * FROM haha';

$result = pg_query($query) or die('Query failed: ' . pg_last_error());



// Printing results in HTML

echo "<table>\n";

while ($line = pg_fetch_array($result, null, PGSQL_ASSOC)) {

   foreach ($line as $col_value) {

       echo "\t\t<td>$col_value</td>\n";

   }

   echo "\t</tr>\n";

}

echo "</table>\n";



// Free resultset

// Closing connection
