Hi Guys, I am facing great problem, have tried different methods now I m completely annoyed :'(. I want to maintain the location on the memory accessed by all the sessions I am working on some application where I m suppose to make communication among sessions. So I though of using semaphore(shared memory with mutual exclusion) in PHP. I don't know why the script always create new memory location with same key when ever I open the page, instead it should maintain the pointer, with the value. In example below, when ever I change the value for location "1234"(shmop_open(1234, "c", 0644, 1)) still the value remains one or I think php creates new location have same key("1234") with value one. I think when ever I open the page it creates new thread, and every thread creates new location on the memory. I dont know how to stop this. Example: <?php $shm_id = shmop_open(1234, "c", 0644, 1); if(!$shm_id) { echo "Error while creating the shared memory segment.\n"; } else { echo "Memory created"; } $shm_bytes_written = shmop_write($shm_id, "1", 0); if($shm_bytes_written != strlen("1")) { echo "Error while writing data\n"; } $my_string = shmop_read($shm_id, 0, 1); echo "....Value.... =". $my_string; shmop_close ( $shm_id ); ?> (I can provide you with my attachment) please go through this.
