You can't check since session write happens _after_ the execution of your
script. You could check if ini_get('session.save_path') is writable, or if
you are able to create a temp file with some contents on it, but that won't
tell you exactly if session writing will be successful - too many different
parameters:
- what will the size of your session file be?
- after your check, how many session files will be written by other
instances until it's your turn?
- the complete disk usage may change, since you're in a multi-user
multi-session environment...
Better: make a check if there's enough space left on the session.save_path,
on a regular basis (hint: cron job). Make this job either send you an
email, or delete orphaned session files (generate a listing and walk it by
last access date).
