The shmop implementation as described in this help page is acttually merely a ramdisk / tmpfs that exists only within php, and even only on the linux servers. Or am I missing something?
On windows, the very same functionality can easily be achieved by creating such disk.
In fact, on my own server, I do use a tmpfs disk instead of the - as it appears to me - limited shmop feature.
Why not implement a $_SHARED or $_MUTUAL SuperGlobal in which we can create variables at will, and that is shared by all connections?
This would greatly improve performance of many PHP applications, and could save a lot of burden on server memory. Especially if those variables could be classes containing functions.
You could implement that it is up to the programmer to guard atomicity.
Such superglobal would be feasible on windows servers as well.
