I don’t think your code got pasted right. Use
[code lang=”php”] … [/code]
to paste properly.

what do you think about this solution? (Runs on Linux (slackvare) 2.6.27.7)

PHP 5.2.11 (cli) (built: Oct 2 2009 17:30:20)

require_once( 'Thread.php' );
if ( function_exists('sem_get') )echo "sem";
// test to see if threading is available
if( ! Thread::available() ) {
die( 'Threads not supported' );
}
// function to be ran on separate threads
function paralel( $_limit, $_name ,$lock) {
sem_acquire($lock);
for ( $index = 0; $index start( 10, ‘t1′,$s1);
$s2 = sem_get(2);
$t2->start( 10, ‘t2′,$s2);
// keep the program running until the threads finish
sem_acquire($s1);
sem_acquire($s2);
/*
while( $t1->isAlive() && $t2->isAlive() ) {}//*/
?>

Why use the loop to keep things alive?
You can just set the time limit to 0 and only when one thread closes you can check if there are any other working if not exit.
I think you might spare some resources.
I am working a lot with socket listeners built in PHP and Python… so they are never supposed to stop and the PHP version works very neat like that using quite few resources.

My post is about achieving multithreading in general, not on a specific case. Of course, you are limited to the single main thread of PHP but which can spawn multiple child threads by interoping, for example, with .net.

You can think of it like this: PHP thread would pass a list of “operations” to be executed on different threads by .net. Instead of having them waiting one for eachother, they could run in parallel. Of course, you can not overcome the limitation of the PHP thread, but there is still a slight gain on performance.

If you are talking about Windows, in most of the cases the discussion involves .NET. Of course..you can achieve multithreading by interoping with Java, C++ etc., but since .NET always come in handy for me, I can recommend you this http://www.facebook.com/note.php?note_id=281965971827784
