dealing with binary data

[agravayne]

Hello,

 

I am trying to deal with binary data - and am completely new to this - via PHP. What I am doing is emulating a device that will post to a socket server. I have a client page that emulates the device and a listening server that deals with data posted to it. What I have need to do in order to emulate this is create some binary data and post it - then read the binary data back in and deal with it appropriately.

 

Any ideas? I though about creating a file on the client side then reading that file in on the receiving side - but not sure how to create a binary file?

 

Any pointers?
