Sometimes it 's better to chew some gum instead of speaking
This way you get better chances of not exposing your ignorance.
For starters, it 's not the webserver that interprets the code, it 's the php engine - which you can have it installed as a web server module or standalone using the FastCGI protocol (google: php-fpm).
When you want to run a PHP file, it compiles the source to bytecode.
Since you seem to not even understand what bytecode is, let me draw it for you
Read it a few times to absorb it.
Then the bytecode gets executed by ... let 's see by whom:
a) in case of the vanilla PHP, by the PHP Interpreter.
b) In case of the HipHop VM, by the JIT compiler
PHP does not have to recreate the bytecode every time we want to run a script, although that is the default behavior in many installations. In contrast, we can choose to cache the bytecode and keep using it forever without parsing the source again (google: php apc).
No shit Sherlock.
And as I already said before, PHP compiles to bytecode as well. Of course, PHP does not call that "MicroSoft Intermediate Language"
The reason you are confused in your head about this (apart from your ignorance of PHP internals) is that you don't get to see the bytecode in PHP. No .jar files, no .exe files. It gets passed directly to the interpreter or stored in a caching scheme and called from there.
And given that you have no idea what you are talking about on this particular "ONE of the reason", I can about the quality of the rest of the thing you might have said.
