Re: shmop errors

You have the same script try open the shm segment 2 times, which is WRONG. Here is a proper example of what you should be doing: <?php define("SHMKEY", 0xDEAD); define("SEMKEY", 0xCAFE); if( !($shm_id = shmop_open(SHMKEY, 'c', 0644,10)) ) { exit("Segment already exists and you do not have write permissions to it, or you cannot create a new segment\n"); } $data = shmop_read($shm_id, 0, shmop_size($shm_id)); shmop_close($shm_id); echo $data."\n"; ?> I've also committed the patch to CVS that should eliminate the warning message. I wonder why Zend required strings with defined length to be null terminated, sounds like a recipe for disaster, if the length is known it should be used. But, whatever, please try the latest CVS.
