Dear group,
I am trying to query my db and print the results.

except a blank page. can any one please help me what
is going wrong with my script.

Script:

$conn = pg_connect("user = $user dbname = $dbname host
= $host password = $pass");
if (!$conn)
{
echo('could not establish connection with
database <br>');
exit;
}
$sql = "select * from experiment;"
$sth = pg_exec($connect,$sql)
if (! $sth){
die("Can't execute query".pg_errormessage());
}

for($i = 0,$j = pg_numrows($sth);$i < $j;$i++){
$ar = pg_fetch_row($sth,$i);
foreach($ar as $col){
print "$col ";
}
print "\n";

well here a few things. 1. Have you setup your php.ini file
to log errors to your apache error_log file or a unique
php_error.log file

2. Lines $sql = "select * from experiment;"
$sth = pg_exec($connect,$sql)

are both missing sem-colons


also once you establish that errors are going to your lof files the rest
should be a peice of cake


Good luck
