Problem with pg_fetch_array

Hi I am trying to display the rows from a database table in a grid. I retrieved the results using pg_query() with a Select command. pg_query() returns true. But when I pass the results $rows to pg_fetch_array(), it returns false. I even tried displaying the error, if any, using: pg_fetch_array($rows) or die('fetch array failed: ' . pg_last_error()); I also tried pg_result_error(), but both didn't display error. It just displays "fetch array failed: ", but it doesn't display any error. When the pg_query() returns a result, I wonder why pg_fetch_array() is not able to iterate through the rows. I am new to this PHP database stuff, please help me in this. Thanks Vignesh.
