[SOLVED] UK Postcode Distances

[rarebit]

Hi, i'm looking into doing a module for a CMS which needs to check distances based upon postcodes (in the UK). I found this, which I implemented and sempt to get strange results, so I used this function (which is actually basically the same) and also checked some GPS data here. But I still get the same results, being:

Sheffiled (S1) -> London (SE1) is 93.827627581918 miles

Sheffiled (S1) -> Leeds (LS1) is 5.4432310738348 miles

but:

Sheffiled (S8) -> Leeds (LS1) is 4.8989079690129 miles

and S8 is on the other side of the city (further away)... *** This could be an indicator to the issue!

P.S. I'm not wanting to use the Google Maps API!

I have no idea, but I did find you This link.  It may be the answer to your problem.

if you have a database of UK postcodes with their lat and long coordinates you can calculate the distances.

Cheers Barand, after realising my 'latitudes' were all defaulted it works like a treat, just how I was going to amend it too, the other version even works now.

 

That one you referenced jonsjava doesn't give the required php (prolly can use ref's above) and also has a great big copyright on it...

 

Solution found which will make for a great bank holiday weekend, cheers for the help guy's!
