Hey Erwin,

It's just an experiment of mine, nothing production-related... YET :-)

The thing goes like this. I have a script that's supposed to do an
action on lets say 100 different hosts in the same time. So I need
multi-threading ar a way to emulate it. My approach was this:

$threads=array();
$responses=array();
foreach ($hosts as $host)
$threads=fopen('http://domain.with.the.script/path/to/script/
script.php?op=action&host={$host}','r');

foreach ($threads as $thread_id=>$thread)
if ($thread)
{
$responses[$thread_id]=''
while (!feof($thread))
$response[$thread_id].=fgets($thread);
fclose($thread);
}

So now the threading part is emulated through Apache, making
concurrent requests to the script.php that contains the actions to be
undertaken and specifying the host that I want to be the target of the
actions.

Basically that's my approach to multi-threading emulation in PHP.

So...any suggestions/ideas/anything? :-)

I am really curious about other approaches because this multi-
threading thing in PHP seems rather disturbing because of it's
absence. :-)

Where are you creating new threads?

I agree with Erwin - if you need to use threads, PHP isn't a good way to
go. If you really need this and it's has to be in PHP, I'd look at
spawning multiple processes off and do the work in batch mode, perhaps
saving the results in a database.

But personally I'd be looking at another language such as Java or C/C++
which has good thread support.

Yeah, I would go the C way myself, but it has to be PHP...
