problem with session_start()

[jonwondering]

I have the following piece of code:

<?php

session_start();

function Login($username, $password)
{

	// If user was in the middle of filling out new account form,
	// and decided to login, then clear all the junk the user filled out.
	if ($_SESSION['signup_account']) {
		session_destroy(); // line 11
		session_start();
	}

}

?>

and I got this error today from the error logs:

PHP Warning:  session_destroy() [<a href='function.session-destroy'>function.session-destroy</a>]: Trying to destroy uninitialized session in /home/username/public_html/checklogin.php on line 11

doesn't it count as session_start() when it's outside of the function? or am i missing something else here?

The logic makes sense...
Can you reproduce the error?

Not sure, but may have to do with you starting the session outside your function ?
You could try this:

if ($_SESSION['signup_account']) {
            if(isset(session_id())) {
            // If a session was started at this point, destroy it and start a new one
            session_destroy();
            session_start();
            } else {
            // If no session exists, start one
            session_start();
            }
