Say we use this query for an example:
If the DB column you wanted to get data from was called "example", you'd use this to call the data:
The outputted data is whatever was stored in the column you called.

And how do I show the queries on forum (thread)???
I do not know how to use it, please help me. Thank you very much :)

(Normal PHP is: ex:

$result = mysql_query($query);

while($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
echo {$row['threadid']}".
"{$row['title']}".
"<br/>";
}
