PHP - Getting coordinates based on address

I have attached here the class and a test file so you can see how it works.
I plan to develop this class in the future that’s why it requires a Google Maps API key.

Here is the test file for it, just to make an impression on how it looks like :

PHP [Show Plain Code]:

1. <?php
2.  
3. //include our class
4. require_once(dirname(__FILE__) . ‘/class.googleHelper.php’);
5.  
6. //your Google Maps API key (you can get one for free from http://code.google.com/apis/maps/signup.html)
7. $apiKey = ‘API_KEY_HERE’;
8.  
9. //init our object
10. $obj = new googleHelper($apiKey);
11.  
12. //get coordinates and print the debug info
13. $address = ‘Danmark, Sjælland, Hørve, Dragsholm Alle 4534′;
14. print ‘For our "’ . $address . ‘" we have these data : ‘;
15. print ‘<pre>’;
16. print_r($obj->getCoordinates($address ));
17.  
18. ?>
