zend search lucene - Efficient, database-independent PHP implementation of geospatial index? Zend_Search_Lucene extension? -


i'm storing lat/lon information in mysql database, doesn't have great geospatial search support. i'm maintaining separate lucene text search index efficient full text search, looked @ geospatial extension lucene; seems available java implementation, not zend_search_lucene php version use.

is there similar allow me maintain separate, database-independent geospatial index? implementation of r-tree variant in php or similar? geospatial extension zend_search_lucene?

it'd need allow efficient geospatial queries, within-radius-of-x , within-bounding-box-y queries, , return id of entry in database.
