ok nerdzors, look out. Ira told me about a project that she made that took an analog input from processing and posted it to php (and then possibly a database, not sure). i wanted to try it out for myself, so i did some searching, and of course the processing guru Daniel Shiffman had a nice tutorial on at least getting to a php script.
the php script writes to a text file that you are calling from processing. The php script i am using in this first draft is the same as Shiffmans here. once you have that up and running with all the correct permissions set on the file (read+write), you can fire up processing.
I modified his example file so that the sketch loops and constantly checks the script (+ text file) online, and updates the sketch accordingly. I inadvertantly created a collaborative drawing tool. Potentially, an infinite number of computers/machines could connect to this file that are running this processing sketch, so jessica, nick and i had a collaborative drawing session at 2 in the am.
