SendNetworkString in PHP loop [Resolved]

[Kwai chang caine]

Hello at all

I have a PHP code with loop for watching evenement in the server
For the moment, for break the loop i use a simple empty file "Stop", when the PHP loop see this file, it break the loop

But i try to sending data to this PHP code during this loop and that not works with POST or GET
I begin by automaticaly PostEvent a POST method, and apparently the PHP not read the next manual $_POST or $GET variable in the loop
I have try to unset the $_POST variable, but that not works too

Someone have a way for do this ?

I think you misuse php.

You can write standalone codes and you can write web pages.
If you write web pages, I think the content of the environment variables are only set once at start of the php script.
So they will never updated in your 'while' loop.

Aaaah !!!! ok ... A way in less
Furthermore, it's impossible to have variables between sessions
It's really difficult to quickly communicate between PB and PHP and in the other direction

My project works now in the first try but as i expected it's a little bit slow
So, for fix a part of the slowness, i search better ways for communicate in both ways

And by dint of searching, i have found the WebSocket...it's the reason of my other question where you have also answered
viewtopic.php?p=561254#p561254
But WebSocket is really not simple to use between PHP and PB, and i have search all the afternoon yesterday and not found examples really working for me, even between PHP and HTML

Thanks for your precious help
