php - Trouble logging out / destroying session -

im having problem destroying session on little test-side made.

i can log in code_login.php file, , header() other page, login required. when log out, can go page though logged out.

(session_start() @ top of pages)

this login code:

$res = $db->query($sql); $num = $res->num_rows; if ($num == 1) { $_session['user'] = array( 'username' => $username; ); }

here logout:

session_start(); $_session = array(); session_destroy(); header('location: index.php?loggedout');

this top of page login required

session_start(); if (isset($_session['user'])) { require stuff; } else { header('location: index.php?loginneeded'); }

but still able go loginrequired page, after logging in.

session_start();

is inserted on every page set or unset session reading session

data
