Unlike, say, C preprocessor instructions or java's imports, php
include() is executed when your script runs, not when it compiles. When
interpreter encounters an "include", it reads the given file and
evaluates its context as php code. "include" is just a confusing name,
"included" files are actually not "embedded" in main file.
