Do you know me do you know the process inside a php file compilation.
PHP files are often construed, not put together - the interpreter compiles them internally to bytecode, but that's something done instantly whenever a script is invoked, not something made by the programmer.
Really surprised to determine the number of compilers you will find available. @student, you might like to take a look at http://en.wikipedia.org/wiki/PHP#Compilers for more info. Appears like you will find a variety of compilers that compile to bytecodes java, c++, et al. Facebook infamously compiles their PHP to C++ and machine now too.
