Problem with PHP and PostgreSQL - Mailing list pgsql-php

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.phpon line 108 

Warning: pg_fetch_row(): supplied argument is not a valid PostgreSQL result resource in
/var/www/html/PMS/csv_export.phpon 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,
