phpsessid is the default name of the session cookie sent from the browser to
PHP. So it becomes part of the $_COOKIE array, which PHP automatically
turns into a global variable for you.
Therefore I use $_COOKIE['phpsessid'] to retrieve it.
But often I use session_name() to replace phpsessid with a more descriptive
name. In that case, the key in the cookie collection is changed
accordingly.
So it seems there's nothing special about phpsessid other than it being the
default cookie name.
