Evaluating a math expression contained in a constant

I could swear this was working before, but now it's not evaluating... I have a constant,
COOKIE_EXPIRE which contains the value '60*60*24*14'. To evaluate this as a math expression I've had to explode it based on the * and reform the entire string by hand ($aExp[0]*$aExp[1]*$aExp[2]*$aExp[3]).

Is there any quicker/easier way to have that constant evaluated as is?

Nevermind, figured it out.

I need to remove the quotes from the constant definition.

PHP Code:


			
define('EXPIRE', '60*60*24*14'); // doesn't eval
define('EXPIRE', 60*60*24*14); // does

...oy. Next question then, if you're defining a constant using variables, such as from a database:

PHP Code:


			
while ($row = mysql_fetch_assoc($pResult)) {
    define($row['cfg_name'], $row['cfg_value']);
}

It seems to assume that the values are quoted. Is there a way to tell it not to for certain values? Hmmm...
