On the subject of maps, I was wondering if anyone has any php code to convert between OS grid references or GB OS easting / northings and longitude and lattitudes?
It's not php code but I have scraped streetmap.co.uk [1] in the past for quick scripts and one-off's. I can also confirm that the conversion is very accurate having converted points back and forth.
