pthreads

Коментарии

Note that this extension *is* a high level implementation of POSIX threads, including on Windows (which is why pthreadsV*.dll is required)

Hello,

WARNING : When using Stackable objects in callable functions by your Threads, you must be very careful if you use it as an array. Indeed, if you do not copy your Stackable "array" in a local variable, the execution time can drop drastically !

Also, if you want to modify an array() in a function, you will also store in a local variable in order that your array is in a thread-safe context.

If you try to test threading, remember to let php think slow:

Skript: -- C:\Webserver\htdocs>php mttest.php

<?php
class My extends Thread{
    function 
run(){
        for(
$i=1;$i<10;$i++){
            echo 
Thread::getCurrentThreadId() .  "\n";
           
sleep(2);     // <------
       
}
    }
}

for(
$i=0;$i<2;$i++){
   
$pool[] = new My(); 
}

foreach(
$pool as $worker){
   
$worker->start();
}
foreach(
$pool as $worker){
   
$worker->join();
}
?>

Output: -- C:\Webserver\htdocs>php mttest.php

If you leave sleep() out, the cpu-time for the threads is long enough to complete the script at once.

Here are some notes regarding PHP pThreads v3 that I have gathered:
-namespace: It does not understand namespaces. 
-globals: It won't serialize GLOBALS at all! And will not register new ones.
-classes: It registers new classes okay.
-functions: Will not register ANY functions - they must all be in static classes. It does understand PHP native functions. 
-consts: previous constants will transfer over. Don't make any new ones thou!
-pThreads only work in CLI - of course!
-If a thread crashes it automatically gets recreated.
-In order to 'force kill' any thread the parent must be killed. Or wait until all other tasks queued are complete and then terminate.
-Anything registered in a pThread does not seem to join the main thread ... which is good!
-pThreads seem to be very powerful on multi-core environments, just need to be careful on system resources... it can and will lock up a system if mis-configured.
-Finally, finding help for PHP pThreads is slim to none... especially v3!

Good luck!
