Question

Possible Duplicate    What is the difference between session unset   and session destroy   in PHP        What is the best for security  and if the session is unset are load times better the next time the session has to accessed rather than recreated

User · Accepted Answer

Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.

It really depends on your application as to which one you should use. Just keep the above in mind.

unset($_SESSION['name']); // will delete just the name data

session_destroy(); // will delete ALL data associated with that user.

Something to be aware of  the   SESSION variables are still set in the same page after calling session destroy   where as this is not the case when using unset   SESSION  or   SESSION   array    Also  unset   SESSION  blows away the   SESSION superglobal so only do this when you re destroying a session   With all that said  it s best to do like the PHP docs has it in the first example for session destroy
