No need PHP code is 'compiled' into an intermediate language which is
interpreted by the zend engine which is written in (c? C++?) and so runs
machine code on the processor, which takes the machine code like PUSH
AX interprets it into machine code instructions like 'move this register
onto the data bus a and put the contents of that other register on the
address part of the bus, then issue a write memory bit pattern to the
bus and increment this register' .
