Considering that my other profession is Geophysicist, I'm kind of up
on those sort of things. The Earth is an oblate spheroid and the
computation to include the curvature of the earth would be a bit more
involved.

I should point out that this is really just trig and is only an
approximate distance as the crow flies. Not even sure if it takes the
curvature of the earth into consideration, but
This is what I have:
$distance = number_format(ceil(69*rad2deg(acos(sin(deg2rad($ulat)) *
sin(deg2rad($vlat)) + cos(deg2rad($ulat)) * cos(deg2rad($vlat)) *
cos(deg2rad($ulong - $vlong));
where:
$ulat = latitude of user #1
$ulong = longitude of user #1
$vlat = latitude of user #2
$vlong = lo

That's the best way: then just do something like:
Here's how I do it in SQL, but the principle is the same in PHP, so I'm
