Topic awaiting preservation: semaphore? & sessions? (Page 1 of 1)

Are there some tutorials for using sessions/php?

Can anybody tell me what a semaphore file is? The referrers script at http://littlegreenfootballs.com/weblog/ uses this file, but i have no idea what this could be...

Thanks.

ok. im no expert at that, but i think semaphore is like a temporary memory. like a pipe or something like that. where more processes can access.
but this may be wrong.

for the session tutorial, i am also interested in one, cause they are a pain in the ass sometimes. especially when you have differently configured servers.

Semaphore file....:

DESCRIPTION
A semaphore is a non-negative integer count and is generally used to coordinate access to resources. The initial semaphore count is set to the number of free resources, then threads slowly increment and decrement the count as resources are added and removed. If the semaphore count drops to zero, which means no available resources, threads attempting to decrement the semaphore will block until the count is greater than zero.

But what its used for in your case... no idea...
