Java -> PHP

[Julia]

Hallo Leute!
könnt Ihr mir helfen? Wie kriege ich die folgende Javascript-Funktion in PHP konvertiert?

function SunPosition(TDT)
{
  var D = TDT-2447891.5;

var eg = 279.403303*DEG;
  var wg = 282.768422*DEG;
  var e  = 0.016713;
  var a  = 149598500; // km
  var diameter0 = 0.533128*DEG; // angular diameter of Moon at a distance

var MSun = 360*DEG/365.242191*D+eg-wg;
  var nu = MSun + 360.*DEG/pi*e*Math.sin(MSun);

var sunCoor = new Object();
  sunCoor.lon =  Mod2Pi(nu+wg);
  sunCoor.lat = 0;
  sunCoor.anomalyMean = MSun;

sunCoor.distance = (1-sqr(e))/(1+e*Math.cos(nu));   // distance in astronomical units
  sunCoor.diameter = diameter0/sunCoor.distance; // angular diameter in radians
  sunCoor.distance *= a;        // distance in km
  sunCoor.parallax = 6378.137/sunCoor.distance;  // horizonal parallax

sunCoor = Ecl2Equ(sunCoor, TDT);

sunCoor.sign = Sign(sunCoor.lon);
  return sunCoor;
}

Daaaaaaaake
