[PHP] sessions

[Pablo Oliva]

I have read that in order to account for browsers/users who do not have
cookies enabled, that you should append the session id to the url (query
string).  Now, if I do do that,
www.site.com?phpsessid=gafklgjr952344afgfa, do I have to do anything so
that I force php to recognize the session id in the query string?  To
clarify my question, does php recognize the session id in the query
string by default if cookies are dissabled?
