PHP to Java (using PtoJ)

Question

I would like to transition our codebase from poorly written PHP code to poorly written Java, since I believe Java code is easier to tidy up. What are the pros and cons, and for

Answer 1

P2J appears to be offline now, but I've written a proof-of-concept that converts a subset of PHP into Java. It uses the transpiler library for SWI-Prolog:

:- use_module(library(transpiler)).
:- set_prolog_flag(double_quotes,chars).
:- initialization(main).

main :- 
    Input = "function add($a,$b){ print $a.$b; return $a.$b;} function squared($a){ return $a*$a; } function add_exclamation_point($parameter){return $parameter.\"!\";}",
    translate(Input,'php','java',X),
    atom_chars(Y,X),
    writeln(Y).

This is the program's output:

public static String add(String a,String b){
        System.out.println(a+b);
        return a+b;
}
public static int squared(int a){
        return a*a;
}
public static String add_exclamation_point(String parameter){
        return parameter+"!";
}
