Drupal Gotcha : Cache_get() Returns Expired Items

	cache_get() returns $cache objects even if the cached item is stale (expired)

	function custom_fn_get_data() {
	// Return the cached data
	$cache = cache_get('custom:fn_get_data');
	if (!$cache) {
	// Some expensive processing to build the data.
	$data = complicated_recursion_and_loops_on_lots_of_data();

	// Cache the data and rebuild it every hour

Drupal 7 Location Calculate distance between 2 location fields

	Location module has the function location_distance_between() (also in D7).
	It passes the call on to function earth_distance($longitude1, $latitude1, $longitude2, $latitude2), which lives inside the earth.inc file in the same package.

	See also: http://en.wikipedia.org/wiki/Great-circle_distance, which points out some of the intricacies of numerical calculation and accuracy of long vs short distances.
