server side Globally acessible variable that can accessed and managed by multiple clients

[grvpal14]

I want server side global variables that can be accessed and managed by multiple clients???

 

For Ex--

 

A user opens the game in browser and assign value to a variable then all other user playing that game see the change in value of

that variable.

[Csharp]

You need to write and read it to a file / Database or any other persistent saving mechanism.

There's no global variable for that. But you can achieve something similar with classes.

 

Hope this helped.

Here is a different idea: shared memory.

 

Take a look at the doc: http://php.net/manual/en/book.shmop.php

 

Using semaphores to lock/unlock the shared memory.  Then it as readable and writable by all php scripts running.

 

Very quick as well.  Much quicker than using a database and with much less overhead.

 

Though, for a simple variable memcached or something could perform the same function.  I needed more control than memcached provides in my system for certain tasks...
