Adding to Martin's and Pieter's suggestions:
 * you use isfile() which does stat() call anyway, so use getsize() instead
and allocate buffer all at once (as Martin said file is held in memory
anyway)
 * you *must* check the path against limited set of directories to send
from, even if you will run server in fully controlled environment (and use
realpath() for checking)
