Hi Andrew,

Thanks for your help. I'm still confused though.

The variable $this->queryresult = pg_exec($db_conn, $query)
which is:

$query = SELECT * FROM oto_sessions WHERE session_id='0pmymn7zXZ8ldBE8SHmA'

If I print($this->queryresult); I get "Resource id #2" which to my
knowledge is the correct output, although I am definitely NOT an

There are 5 fields in the DB and the first 4 are filled with
session_id, session_ip, session_datetime, session_lastaction,
session_userid(which is NULL).

The query is correct and should return a value, but even if it is NULL
does anyone know how I can stop the error message or get it the
function to return a NULL value?

There is DEFINITELY some horrible Infinite Loop there somewhere. If I
do the following:

>> 109     while ($row = @pg_fetch_array($this->queryresult, $c)) {

to avoid the error message it gets stuck in a loop until it times out.
