How to use session?

how can i use session that users can make playlist…

it would help if you explain why you need to use a session to make a playlist.

otherwise just simply use session_start() and then store the playlist in a session variable.

well i search for a player
i found this
that is taking playlist url in XSPF format
this is url of player

can i add automatic url in that when user click on add
or any other good player which become competible with Php script
