How to Get confirmed BP

Hi All:

i developed a page in php, and this is framed in ic web client in order to display extarnal data from another db,

but i need to parse the confirmed bp number to my page something like this:

<iframe frameborder = "0" width = "100%" height = "100%"

src = "http://localhost:<port>/<mypage>.php?data=<BP_Number>"/>

my question is how do i get that bp_number?

Thanks & Regards
