$data = mysql_query("SELECT * FROM phpbb_posts ORDER BY post_id DESC LIMIT 4")
or die(mysql_error());

Above is my code and I'm having problems with the Limit part.
When I first set it, everything seems perfect, but I could come back in a few hours and look at the page again and a different number of records could be shown, even though the code is exactly the same.

Bunu nasıl düzeltebilirim Herhangi bir fikir?
