Question

Fifo queue to commincation between php and c++ apps.

Asked by: solofe

I wrote a c++ daemon to communicate with a telephone device with a micro.
I would use the daemon from web via php pages.
I think that I have to use a fifo queue to send command from php to daemon and to receive response from c++ daemon.
But I'm new to PHP and I studied but never used fifo in c++. Can anyone help me theaching where I have to start?
Thanks,
Federico

Would need more information on the commands and how your communicating to be more helpful.

 But for a First In-First Out queue you could use an Array and its push/pop methods:

http://us3.php.net/manual/en/ref.array.php
http://us3.php.net/manual/en/function.array-push.php
http://us3.php.net/manual/en/function.array-pop.php

Basically make php.net your homepage for awhile ;) The search field in the upper right will help you find endless functions and help.

How exactly do you want to send the command to the daemon, via a command-line op, a socket connection, etc.?  That would be a good start to knowing which direction to point you in.

I would send data to the daemon via a socket connection.
I had a thread in the daemon process to send command. I would that this thread receive commands (messages) from php.
Thanks

array_push and array_pop are lifo functions (last in, first out).  to get fifo, you could push the element on (array_push) and use array_shift to get the first one out.

http://us2.php.net/manual/en/function.array-shift.php for array_shift.  array push is above
