位置距离经纬度计算
mysql 经纬度转换距离查询
$lng //经度
$lat //纬度
方案1:
select id,address,lng,lat,round(6371*acos( COS(RADIANS($lat)) * COS(RADIANS(lat))*COS(RADIANS(lng) - RADIANS($lng)) + SIN(RADIANS($lat)) * SIN(RADIANS(lat)) ),4) as distance from table order by distance asc
方案2:
select id,address,lng,lat,round(6371*sqrt( pow((PI()*(abs(`lat`-$lat))/180) * cos(PI()*(`lat`+$lat)/360),2) + pow((PI()*abs(`lng`- $lng)/180),2)),4) as distance from table order by distance asc
