Hello all,
I currently have a php function that takes two airport codes and returns
their distance in miles. The function gets the longitude and latitude for
the airports from a mysql db. My current problem is I have to show the user
all airports within a certain mile radius of the one they selected. I can't
run this function against all 7000+ rows in the db and return only the ones
needed, how can I do this? I know I have seen this several places online.
Thanks,
Eddie
