请教内存共享的问题！

代码如下：

这段代码报错，请问是怎么回事？

PHP Warning:  shmop_read(): no shared memory segment with an id of [1946257823] in /home/admin/codes/php/shmop/client.php on line 8Warning: shmop_read(): no shared memory segment with an id of [1946257823] in /home/admin/codes/php/shmop/client.php on line 8

回复讨论(解决方案)

$cont = shmop_read($shmid, 0, "Hello");

$cont = shmop_read($shmid, 0, "Hello");

艾玛，又犯低级错误，非常感谢！
