About

This is simple PHP-like compiler, and you can compile only variable declaration(only integer, char and array) and assignment for this, simple math, if(without else), while, return, print("print" - for integer, "echo" - for constant string, "echoc" - for char). Almost everything a compiler can do writed in exmp.php. The codegen is not the best, as it is made for educational purposes.
