Problem with PHP and PostgreSQL

I am having trouble with the following loops and such and accessing PostgreSQL database.
The errors i get are:

Warning: pg_num_fields(): supplied argument is not a valid PostgreSQL result resource in /var/www/html/PMS/csv_export.php on line 108

Warning: pg_fetch_row(): supplied argument is not a valid PostgreSQL result resource in /var/www/html/PMS/csv_export.php on line 118

Here is my Code Below:
//**** SQL Query
$query_panels = sprintf("SELECT * FROM %s WHERE utctime AT TIME ZONE 'MST' BETWEEN '%s' AND '%s' ORDER BY utctime %s", $MM_param1__panels,$MM_param2__panels,$MM_param3__panels,$MM_param4__panels);
//**** Count Fields
$fieldcounts = pg_num_fields($query_panels);
//**** List fields as first Row
for($i = 0; $i < $fieldcounts; $i++)
{
$fieldtype = pg_fieldtype($query_panels, $i);
echo "$fieldtype->name";
if ($i < ($fieldcounts-1))
echo ","; else echo "\n";
}
//**** Output each row of Data
while ($myrow = pg_fetch_row($query_panels))
{
for($i = 0; $i < $fieldcounts; $i++)
{
$fieldname = pg_fieldname($query_panels, $i);
if ($i < ($fieldcounts-1)) echo $myrow[$fieldname] . ", ";
else echo $myrow[$fieldname] . "\n";
}
}

Why do i get those errors?
Why is it not a valid result resource?
any help would be awsome.
Thanks,

You need to connect to the database and execute your query:

$conn = pg_connect("dbname=bigdb host=myserver user=me2");
$query_panels = sprintf("SELECT... ;
$res = pg_query($conn,$query_panels);
$fieldcount = pg_num_fields($res);

etc...
