I need a script for calculate distance between two aeroport

the user will enter the departure city and arrival city, then we will calculate the distance,

Thanks for your help

 

Do you mean difference in flight paths? or direct distance? All you would need to do is find the lat-lng for each airport then calculate the distance between them

 

i mean direct distance between two cities, can you tell me how i get the lat-lng of each city
thanks

 

Geocoding (getting latitude and longitude of a location) is part of the Google Maps API. Here's a link to it:

http://code.google.com/apis/maps/documentation/javascript/v2/services.html#Geocoding

Also, part of the Google Maps API allows you to calculate the distance between two geocoded points. Here's a link to that:

Thanks brother

 

get the lon and lat and then use something like this http://www.zipcodeworld.com/samples/distance.php.html

 

you can get calculation directly from gmaps api or convert distance between 2 lat/long coordinates mathematically (no need of api or other tools). if you need help let me know.
cheers and good luck!
