Hi, one more question. Why the variable, that contains NULL value appears to be not set. When you try to echo it the php does not produce warning about using undefined variable. //$connection contains database connection handler $result=mysql_query("select NULL as value",$connection); $tmp=mysql_fetch_array($result); $foo=$tmp["value"]; if (!isset($foo)) echo("\$foo is not set but does not produce warning -$foo-"); OKi98

Someone correct me if I'm wrong but it appears that you should be using if(!isset($tmp["value"]) before assigning to $foo if you want to ensure that $foo will, indeed, be set.

Yeh - you need to check before you do the assignment. -- Postgresql & php tutorials http://www.designmagick.com/
