creat a data file with the desired information that php can read,
use mIRC to update the file localy, then use sockets to connect to your ftp server and upload the file
php can read the file to display the desired data.
if your not very handy with socket scripting in mIRC this may prove difficult. but i'm not gona code it for you .. so keep trying or find an addon someone has already made that does something similar.
hope this was informative.
