You are on very shakey ground here, A compiler can optimise code based on
the symbols passed to it, ie the object code need not resemble to
structure of the source (famous story about benchmarks where the
"compiler" totally removed the test loop as it realised the whole process
was pointless)

As for php, It it partially compiled afaik (partially compiled or
tokenised) and I can't see why it could not be fully compiled to a native
binary in the future (though in doing so you may sacrifice some of its
portability) as an aside the original pascal implementations were
similarly compiled into "P-Codes" whicn then ran on a target binary
runtime.

The results were pretty much as I expected Jave and C# introduce a VM
overhead and php was propably 100% "interpreted" (actually parsed and
run),
I doubt they used an op code cache (such as apc) which can give 2 orders
of magnatude code performance increase
