I just want to get latitude & longitude using the post code with Google maps API.
I am using PHP for development.
How can I do this?
The post code can be from any where in this world.
You can do this using google map Geocoding API. Please find below example, but to correct latitude/longitude and address you need to pass full address along with zipcode.
For more detail please click on below link:
http://code.google.com/apis/maps/documentation/geocoding/
<?php
$url ="http://maps.googleapis.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=false";
$result = simplexml_load_file($url);
print"<pre>";
print_r($result);
?>
