标题: php如何实现腾讯与百度坐标的转换详解
下面小编就为大家带来一篇PHP实现腾讯与百度坐标转换。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧

废话不多说,直接上代码


public function coordinate_switch($a,$b){//百度转腾讯坐标转换
  $x = (double)$b - 0.0065;
  $y = (double)$a - 0.006;
  $x_pi = 3.14159265358979324;
  $z = sqrt($x * $x+$y * $y) - 0.00002 * sin($y * $x_pi);
  $theta = atan2($y,$x) - 0.000003 * cos($x*$x_pi);
  $gb = number_format($z * cos($theta),15);
  $ga = number_format($z * sin($theta),15);
  return ['Latitude'=>$ga,'Longitude'=>$gb];
}

public function coordinate_switchf($a,$b){//腾讯转百度坐标转换
  $x = (double)$b ;
  $y = (double)$a;
  $x_pi = 3.14159265358979324;
  $z = sqrt($x * $x+$y * $y) + 0.00002 * sin($y * $x_pi);
  $theta = atan2($y,$x) + 0.000003 * cos($x*$x_pi);
  $gb = number_format($z * cos($theta) + 0.0065,6);
  $ga = number_format($z * sin($theta) + 0.006,6);

  return ['Latitude'=>$ga,'Longitude'=>$gb];

}
