Hi, Thank you for your answer. I was hoping there were a solution. :-/ It would have been nice as PHP has a large install base and is a quite common element in cheap web hosting solutions. Has anyone else got any more comments or suggestions? In absence of shared memory and threads. What I really must have is some kind of mutex functionality. I will be manipulating files on disk and I don't want two instances to be able to touch the disk at the same time. Is there something I could use for mutual exclusion? If there aren't any dedicated methods, are there 100% reliable workarounds?
