[PHP] passing resources from one script to another
Hi All, I'm developing a small server application that accepts connections on a socket and then launches an interactive session with the client. The server needs to be able to accept N connections. This part is working famously thanks to code I've borrowed and modified from: http://www.zend.com/lists/php-dev/200205/msg00286.html The problem is the dialogue with the client. If I enter into a while loop then the whole script remains occupied and cannot accept new connections. If I try to open a new background process with exec, then I need to pass a resource from the listening script to the dialogue script. However, it seems that I cannot pass a resource between scripts. If I serialize the resource, passing it as a string to the dialogue shell script, then unserialize it in the dialogue script, it's no longer a resource but an integer... Any ideas on how to get around this problem? Can it be done with PHP? Ian -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

PHP doesn't have threads.. and that's what you would need to accept more than a single connection at once. You can simulate thread functionality to a degree using the PHP execution functions here: http://www.php.net/manual/en/ref.exec.php -- Greg Donald Zend Certified Engineer http://gdconsultants.com/ http://destiney.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] passing resources from one script to another
I should have specified that this is a shell script, not a web application. I have a listening process running. The listening process calls another script once a connection is established. This is done via exec. It works; however, I can't pass a resource directly to the other script. Therefore, I've passed the resource to serialize() and pass the resulting string to the other script as an argument. My idea was to unserialize the string in that script. I expected to get a resource back; unfortunately, I get an integer. My question is: is there any way to pass a Resource between scripts?

You can build a message queue into a text file, every message in the queue will contain the pid as identifier of every socket connetion (the client) and the target pid. This is not a fast solution, but it models a messages system that is indipendent from the server. For example, this queue colud be readed from the client every time it launchs an avent, ect.. A question, why don't use session vars? (or an array of them?)

Re: [PHP] passing resources from one script to another
Thanks Greg. That is what I'm doing. The problem remains passing a resource to the script executed by exec.
