But that is just a matter of copying the .bin files into a configurable dire=
ctory. However, as others have said, this is completely pointless. If you ar=
e worried about initial compile latency on initial requests after a deeply o=
f new code then simply run a couple of warmup requests before flipping your s=
ymlink to the new code. Beyond that I can't picture what possible use this c=
ould be. Hiding source code? No chance, getting PHP code from bytecode is tr=
ivial.
