使用JavaScript或PHP从地址返回经度和纬度的基本API

Question

I am quite new to JavaScript and I am looking for a basic API or function that I can feed an address as a string value and it returns me the longitude and latitude of that address. I have a series of addresses in a DB and I want to add the longitude and latitude values for each of them.

Thanks

Find below example using php

<?php
$address ="1600+Amphitheatre+Parkway,+Mountain+View,+CA";
$url ="http://maps.googleapis.com/maps/api/geocode/xml?address=".$address."&sensor=false";
$getAddress = simplexml_load_file($url);
print"<pre>";
print_r($getAddress);
?>

It return all detail you need to get latitude/longitude as below.

<?php
print"<pre>";
print_r((string)$getAddress->result->geometry->location->lat); echo "<br />";
print_r((string)$getAddress->result->geometry->location->lng);
?>
