Īs a workaround, I've written a function that uses headers_list() and header_remove() to clear out the duplicate cookies. This error has been reported to PHP HQ, but they've marked it "Won't fix" because they say you're not supposed to open and close the session during a single script like this. Do this enough times (as you might do in a long-running script), and the response header can get so large that it causes web servers & browsers to crash or reject your response as malformed. The problem with this, is that each time you call session_start(), PHP prints a duplicate copy of the session cookie to the HTTP response header.

When one of your scripts calls session_start(), any other script that also calls session_start() with the same session ID will sleep until the first script closes the session.Ī common workaround to this is call session_start() and session_write_close() each time you want to update the session. I prefer using this class instead of using directly the array $_SESSION.Īs others have noted, PHP's session handler is blocking. Printf ( '%s', print_r ( $_SESSION, TRUE )) Printf ( 'My name is %s and I\'m %d years old.', $data -> nickname, $data -> age ) $this -> sessionState = ! session_destroy () If ( $this -> sessionState = self :: SESSION_STARTED ) * bool TRUE is session has been deleted, else FALSE. $this -> sessionState = session_start () If ( $this -> sessionState = self :: SESSION_NOT_STARTED ) * bool TRUE if the session has been initialized, else FALSE. If you want to handle sessions with a class, I wrote this little class: Ob_gzhandler must be registered before starting the session. Ob_start(), the function order is important for If a user uses ob_gzhandler or similar with Register an internal output handler for URL rewriting. Is enabled, the session_start() function will Read callback returns the saved session data back to PHP session handling. The read callback will retrieve any existing session data (stored in a special serialized format)Īnd will be unserialized and used to automatically populate the $_SESSION superglobal when the Save handler provided by default or by PHP extensions (such as SQLite or Memcached) or can beĬustom handler as defined by session_set_save_handler(). PHP will call the open and read session save handlers. When session_start() is called or when a session auto starts, Session_start() creates a session or resumes theĬurrent one based on a session identifier passed via a GET or POST
