php geohash extension

geohash

php geohash extension (php geohash 扩展)

编译

git clone 到机器

执行：
phpize
./configure
make
make install

然后把 geohash.so 加入到php.ini中

方法

/**
 *  $latitude    //纬度
 *  $longitude   //经度
 *  $precision   //精密度, 默认是12
 *  返回 $precision 长度的 string 
 */
geohash_encode($latitude, $longitude, $precision=12);  



/**
 *  $hash    //geohash_encode后的值
 *  返回 array // Array
 *					(
 *					    [latitude] => 39.416916975752
 *					    [longitude] => 100.92223992571
 *					    [north] => 39.416917059571
 *					    [east] => 100.92224009335
 *					    [south] => 100.92223992571
 *					    [west] => 100.92223975807
 *					)
 */
geohash_decode($hash);

/**
 *  $hash    //geohash_encode后的值
 *  返回 在$hash 8个方向的hash值 （顺序：N, NE, E, SE, S, SW, W, NW）
 *  
 *		  NW N NE
 *		    \|/
 *		  W - - E
 *		    /|\
 *		  SW S SE
 * 
 */
geohash_neighbors($hash);

/**
 *  $precision    //精密度
 *  返回 数组，array("width"=>12.0, "height"=>12.0) 
 *  表示矩形的宽和高
 */
geohash_dimension($precision);

geohash's Issues

没有win的扩展

如题

php8.0编译不过去

怎么办

PHP71: incorrect result for geohash_neighbors: c2b2mvrc

var_dump(geohash_neighbors('c2b2mvrc'));

array(8) {
[0]=>
string(8) "c2b2mvrf"
[1]=>
string(14) "c2b2qj24c2b2mv"
[2]=>
string(14) "c2b2qj21@��"
[3]=>
string(13) "c2b2qj21@�"
[4]=>
string(8) "c2b2mvrb"
[5]=>
string(8) "c2b2mvr8"
[6]=>
string(8) "c2b2mvr9"
[7]=>
string(8) "c2b2mvrd"
}

php7用不了吗,安装报错

geohash_neighbors产生coredump

geohash_decode crash on PHP.7+

After some changes for PHP7:
RETURN_STRING # remove last parameter
add_next_index_string # remove last parameter

I can compile the source, but the function will be core dumped.

能否结合redis的GEO使用？

Redis也提供了GEO服务：
http://www.redis.cn/commands.html#geo

但是redis的geohash值算出来是11位的，而作者该方法算出来12位，是否可以做关联或者后续进一步完善？

介绍文档错误

/**

• $precision //精密度
• 返回 数组，array("width"=>12.0, "height"=>12.0)
• 表示矩形的宽和高
  */
  geohash_dimension($hash);

应该是
/**

• $precision //精密度
• 返回 数组，array("width"=>12.0, "height"=>12.0)
• 表示矩形的宽和高
  */
  geohash_dimension($precision);

另外能不能说明一下这个返回的宽跟高,单位是什么啊
