有一个要求是不能用double类型，float类型也不能用。
那么在mysql中使用什么样的类型存储经纬度比较合适呢？
如果要存为varchar类型，php中两者该如何转换呢？
如果存为int类型，是否要使用bigint，还是说int就能满足呢？

You can use string varchar, and then convert the string into double type or float type

Mysql supports the Geometry type, but it is more troublesome to operate.

Just convert it to plastic storage. If the accuracy is required to be 8 decimal places, multiply it by 10^8 and store it in the database
