For this to work, attrlat and attrlng need to be in lower case otherwise you will get :
"unknown latitude attribute ''"
(PECL sphinx >= 0.1.0)
SphinxClient::setGeoAnchor — Set anchor point for a geosphere distance calculations
$attrlat
, string $attrlong
, float $latitude
, float $longitude

Once an anchor point is set, you can use magic "@geodist" attribute name in your filters and/or sorting expressions.
attrlat
Name of a latitude attribute.
attrlong
Name of a longitude attribute.
latitude
Anchor latitude in radians.
longitude

Returns TRUE
on success or FALSE

When sorting on @geodist you have to use SetSortMode with SPH_SORT_EXTENDED, like below, if SPH_SORT_ATTR_ASC does not seem to work.
$sphinx->SetSortMode(SPH_SORT_EXTENDED, '@geodist ASC');
