Re: [PHP] Threading objects

2003-03-13 Thread alex

As i rember apache can not handle a threading php ... if you whant threads
you need to run php from command prompt in a linux/unix enviroment(windows
dosen't support threads i I'm not wrong).Look for a threads project in 
PEAR(http://pear.php.net/).
Hope it helps,
Best regards,
Alex.
 Is it possible to some how thread a php script threw apache. There has
 to be something you can do, it seems there is always something you can
 do :) What I want is the following.
 I administer a mailing list that has a few hundred thousand subscribed
 recipients.
 I've written a script that runs threw the DB and validates the email
 address.
 First by format then by connecting to the mail server.
 This script takes way to long to run as it has to do one at a time. I
 want to some how thread this so it can be validating multiple emails at
 a time.
 Please excuse my ignorance on the subject my web programming experience
 is rather limited.

 Thanks

 Kris

Re: [PHP] Threading objects

2003-03-12 Thread W. Enserink

i'm not sure what you want. But you have created objects here in $a,$b and
$c.
If you want to order them in a special way you have to write the
functionality of course. I think you have to do this before the object is
created because you define the variables 10,5,1 before the objects are
created. Once the objects are created they themselves don't know nothing
form each other. So th eparent object has to control this, or in your case a
'parent piece of script'.

You can use $a,$b,and $c as regular,ordinary variables.  further on.

hope it helped,

Wilbert

Subject: [PHP] Threading objects


 I want to be able to thread objects. I'm not really sure at all where to
 start. but I want a script where multiple objects are being processed at
the
 same time.
 I have an example php script

 ?

 $a = new sleeper();
 $b = new sleeper();
 $c = new sleeper();

 $a-sleepFor(10);
 $b-sleepFor(5);
 $c-sleepFor(1);

 class sleeper {

  function sleepFor($num) {
   sleep($num);
   echo sorry I was a sleep for $num \r\n;
  }

 }

 ?

 I want so object $c would print then object $b then object $a as the
 sleeping time is less and less.
 Does that make sense? Please ask if you don't understand

 Thanks for any help you can offer what so ever.

 Kris

Re: [PHP] Threading objects

2003-03-12 Thread Kris

Hi Wilbert

Thanks for responding. However I am completely aware of how objects work as
I come from a Java back ground.
If you are familiar with Java at all I'm looking for something like the
PipedOutputStream, PipedInputStream and Thread classes

I want the processes objects to be threaded, therefore processing
simultaneously.
This would mean $c would print first as it slept for the least amount of
time.

All I'm really asking is how do you initiate threading with PHP?
A small example would be nice

Regards

Kris

Re: [PHP] Threading objects

2003-03-12 Thread Mincu Alexandru

I think that he wants a function that acts like steTimeout(..) in
JavaScript ex:
code
setTimeout('alert('tst2')',5000);
setTimeout('alert('tst1')',4000);
/code
When you exec this code in js the first alert that is executed is tst1
and then tst2.
I don't know if you can do this in php without using threads.
I am not sure that this is the only function he whants to use this way,
but if I am not wrong threading dose the job very well.

btw what is the status of that project? Is it functional yet? I havent
read the php-dev discutions on this yet.

Hi,
generally, multithreading (using system threads) within PHP is
impossible, AFAIK. Of course running (apache) processes can communicate
via shm but it is not multithreading. Your code will be executed
sequentially as written. One sleep will start after another ends. There
is not known, to me, solution, sorry :(;

Re: [PHP] Threading objects

2003-03-12 Thread Rasmus Lerdorf

So your problem has nothing to do with threading.  What you need an an 
asynchronous way to connect to multiple sockets and deal with responses as 
they become available.  See php.net/socket_select

Well, web is (or at least should be) kind of real-time, thus you should try
to postpone lengthy actions.

What I'd try (and I already did such stuff with success) is to just create
some DB entries, in your case this would mean to add a validation request
entry to a database, or even simply a todo file.

Another process, most certainly run by a cron job, would then read the DB
(or the toto file) and perform actions necessary. When done it would update
some kind of status flag.

On your website yo could display something like 187322 addresses scheduled
for validation - 123499 to go, or something like that, just by reading the
status data updated by the cron job.
