Is using the in-build PHP session mmnt system professional in a commercial script?
What does it have for drawbacks/advges over a custom mysql session system?
Thank you for your answer.
it really depends on the situation.
it's a yahoo-style directory.
There are no drawbacks. PHPs session handler can be made to use a database with session_set_save_handler(). Any additional functionality you need can either be added into the custom session handling functions required by session_set_save_handler() or layered on top.
Having said that file based sessions tend to be a bit faster.
