Its no longer working. I have tested it on windows machine all i am getting this error. Error: could not write the cache headers: could not write to the cache file

It creates the file but it does not write the file.

This class requires PHP file locking functions to work properly. Depending on your Windows file system, it may not work as file locking is not supported by all Windows file systems. It is a Windows limitation problem, not PHP's.

The problem is dealing with file locking on multithreaded Windows Web servers like IIS. I am afraid two parallel file locking requests coming from different threads does not work on Windows.

there are no parallel requests.. because i am using it alone. Windows is not my production server and i am not fool to choose windows for php production server ;) I tried it on linux and it works fine. Perhaps i have to figure out some way to run it on my development machine.

Thanks

Maybe you should add a method to set off flock when not desired?
It's rather annoying when working under windows dev machine (xampp)

Sorry for the delay.

Without locking you can't assure that two simultaneous accesses will not cause cache file corruption.

Anyway, it seems that Windows problem is more when you store cache files in partitions with FAT file systems.

when flock block the access to the files, is it possible that the other simultaneous requests will hang until the file is unlocked and cause a server crash ?

should the lock be non-blocking using LOCK_NB ?

No, when processes die all acquired locks are released, at least in Linux/Unix.
