PHP flock Manual. I just want to add a note about making atomic lock on NFS, there is only twoways 1 the most robust but the most complicate Its to use link to create ahard link to a file you want to lock on the same FS of course. On most NFS implementations, Link is atomicOnce you created a hard link not a symbolic link, with a unique randomlygenerated name, call stat on it and count the number of link nlink, if thereis only 2 then the file is locked. If there is more than two you have to unlink the link you just created andcreate a new one with a new unique name else NFS will use its cache and statwill return wrong data then call stat on the new link and test the number oflinks again, repeat this operation until you get the lock. You have to use usleep between the link attempts with a fixed randomsleep value to avoid dead lock situations link and unlink may be atomicbut not instantaneousAlso note than when you unlink a file through NFS, if NFS think that the fileis still in use, it will create a. A wrong timing could generate thousands of thosefiles and a deadlock situation. Because of this when a deadlock situationoccurs or if your stat command returns a very high number of links, you haveto look for. NFS take its time to remove them 2 the simplest the second method is to use a lock server and lock daemonson each client that will forward lock request to the server. Here is for reference the function I created to make atomic locks through NFSthis function is in production since at least 4 years now, its just forreference because it uses many external functions to do its job but you can seethe principle http pastey.
