I don't really write anything in PHP, but to manually convert an unsigned 
integer value foo into an IP address you would use a bit shift and a mask 
in the form:

foo & 0xff, (foo >> 8) & 0xff, (foo >> 16) & 0xff, (foo >> 24) & 0xff

Of course this is in C but perhaps it's roughly appropriate for PHP.
