The PHP gurus have really simplified this issue for us. Both the pg_query() and pg_fetch_array() methods return a false if an error occurs. Likewise, pg_fetch_array() returns a false when it has reached the end of the recordset. The following works very well:
if ($result = pg_query($query) and $row = pg_fetch_array($result)) {
do {
// process query results
} while ($row = pg_fetch_array($result));
} else {
// output if error
}
Best wishes
