php delete a session code example
Example 1: php delete session
session_destroy(); // To delete whole session
// OR
unset($_SESSION['myVar']); // To delete a session var
Example 2: session value not removed php
All of a sudden neither session_destroy() nor $_SESSION=[] were sufficient to log out. I found the next to work:
<?php
setcookie(session_name(), session_id(), 1); // to expire the session
$_SESSION = [];
?>
