// The base hashcode length must be a multiple of 5, otherwise it will automatically be filled to a multiple of 5.
// The longer the base length of hashcode is, the more options are available to intercept, and the longer it is recommended. 10 is usually enough.
$hashCodeLength = 10;

$geohash = new ccinn\GeoHash($hashCodeLength);

// Search nearby 20 meters
$interceptLength = 8;
