>From test script:
// test errors
var_dump(shm_stat());
var_dump(shm_stat(1));
var_dump(shm_stat(""));
// open shm segment
$key = ftok(dirname(__FILE__)."/008.phpt", 't');
$shmId = shm_attach($key, 1024);
var_dump($shmId);
// first stat call
var_dump(shm_stat($shmId));
// write data + stat
var_dump(shm_put_var($shmId, 10, '10'));
var_dump(shm_put_var($shmId, 20, '20'));
var_dump(shm_put_var($shmId, 30, '30'));
var_dump(shm_stat($shmId));
// remove data + stat
var_dump(shm_remove_var($shmId, 20));
var_dump(shm_stat($shmId));
// re-open shm segment with different size + stat
var_dump(shm_detach($shmId));
