PHP Session not Saving

Question

I have this written at the very first line on every page of my website.

include(\"restd.php\");

and restd.php contains the following lines

Answer 1

Your session directory (probably /tmp/) is not writable.

Check with session_save_path() if it is writable.

if (!is_writable(session_save_path())) {
    echo 'Session path "'.session_save_path().'" is not writable for PHP!'; 
}
