Yet even simpler example:
$query = "SELECT * FROM atable";
$result = pg_query($query);
if (pg_num_rows($result)>0) {
 while($row=pg_fetch_object($result) {
   echo $row->first_column;
   echo $row->second_column;
   ....
   echo $row->last_column;
 }
}
else {
 echo "The query did not return any data!";
}


flavio

simple pg_num_fields & pg_num_rows example.
$result = pg_query($conn, $string);
while($arr = pg_fetch_array ($result)) {
     for ($x=0;$x<=pg_num_fields($result);$x++)
           print $arr[$x] . " ";
     print "\n";
}
adapted (stolen) from php manual ;)
