using php_proj to convert data

[Bart van den Eijnden]

Hi,

there are some docs inside of the php_proj.c file. I have attached it for
you.

  * 4) pj_transform : pj_transform(PJ pjsrc, PJ pjdst, double x, double y)
  *      transforms coordinates from source projection to
  *                   destination projection.
  *
  *   Example :  $projarray[0] = "proj=lcc";
  *              $projarray[1] = "ellps=GRS80";
  *              $projarray[2] = "lat_0=49";
  *              $projarray[3] = "lon_0=-95";
  *              $projarray[4] = "lat_1=49";
  *              $projarray[5] = "lat_2=77";
  *              $projarray[6] = "";
  *
  *              $pjlcc = pj_init($projarray);
  *              $projarray2[0] = "proj=latlong";
  *              $pjlat = pj_init($projarray2);
  *
  *              $ingeox = 1537490.335842;
  *              $ingeoy = -181633.471555;
  *
  *              $ret = pj_transform($pjlcc, $pjlat, $ingeox, $ingeoy);

Best regards,
Bart
