    Question Quick $_SESSION superglobal array question!

    I've been writing a few sample scripts, using session based logins.

    I know what I'm doing, I'm just curious as to why do some people set $_SESSION = array()?

    Does it make any difference in terms of security by not setting $_SESSION to array()?

    Somebody explain please?

    $_SESSION = array(); can be used to clear the data. ie, like for logging out etc (as opposed to unset()). Also can be used to clear memory.
