Adding Multi-Threading to PHP (Purely New Idea Try it)

[asden]

I had an idea of Adding Multi-threading functionality to php ( i called it PHPThreader ) in little words the idea was :-
1. make a Js class which Creates Ajax Objects in order to call PHP Scripts(Threads)
2. then make a PHP class Implements and Interfaces the Js Class
3. Implement the PHP Class with your script easily and LAUNCH threads very easy Just Like:-
$obj=new Thread($filename,$Inputs); in other words:-
$e=new Thread("Download.php","url="http://phpbuilder.com");

you will find the Classes & Documentation & Examples at :-
http://sourceforge.net/project/showfiles.php?group_id=203377&package_id=242365&release_id=532251
where

AjT.php : the Js Class which is implemented by the PHP class

Threader.php : PHP Class, which is a front to deal with the Js Class

Bag.php : is also dealing with Js Class to know the status of Thread( a finishing Alarm )

There are Two Examples:-
1. Downloading two files on parallel
2. PDM (Php Download Manager) a simple and primitive download manager in php:D

Please tell me what do u think of the Idea & Implementation .Thanks in advance and critique as u wish

Well.... 37 reads and no replies this saddy
Any way i made a second release PHPThreader 1.1

you can get it Here (http://sourceforge.net/project/showfiles.php?group_id=203377)

i added Inter Thread Communication & Synchronization between threads
but please reply tell me what do you think
thanks in advance

Can you really call this threading when it's really separate processes using files to communicate? You might want to use shared memory (www.php.net/shmop) to make this communication faster.

[asden]

Well.... Many thanks to your interest
You might want to use shared memory to make this communication faster.
this is true for large sizes but when the size is small(100/200 Bytes) there is bearly no difference in speed
but you didn't tell me if you benefited or not from the class ?do you think it's an add or it makes live somehow easier?
please you all tell me . Thanks in advance

It sounds to me like you've just made a convenient AJAX class which could be quite advantageous for use in Javascript development. I have not used your class, but for a given page, I don't see how this provides any functional improvement over standard AJAX except that it's easy to use.

Does your code or your documentation provide any functionality to multiplex access to global resources like variables/alerts/etc? This is one of the problems I'm wrestling with as I move into multithreading.

[asden]

Does your code or your documentation provide any functionality to multiplex access to global resources
Yes and the Synchronization of access too
the idea is very simple and depends on what you can call properties or varaibles
let's assume that we have a thread $t1 and another one $t2 then they can tslk as follows :-
$t1->CSet("name","sneakyimp");
then $t2 can access this very simply as
$name=$t2->CGet("name");
and there is a simple Mutex Sync. as $t2 can't read while $t1 is writting
that's how it works
and again i'd like to hear from you all (Esp. in applications point)
Thanks in advance
