I accept that the definition of compiler is open to debate.

I was using the concept that 'compiling' infers converting the entire
'human-readable' source file into a 'machine-readable' executable file (
which can then be 'run'). By this definition, PHP is not a compiler.

Using the definition favoured by you and the OP:
With an interpreted language like PHP, if a function is never called or
an object/class definition never used, it doesn't get compiled.

With a proper compiler (by my earlier def), an unused function will be
compiled, but may then be removed by a later optimisation stage (either
in the compiler or the linker).
