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.
