Error in importing google contacts

Question

I am using this to get all gmail contacts from my id [email protected]:

Import Gmail or Google contacts using Google Contacts Data API and OAuth 2.0 in PHP

However, I get only 30-40/300 contacts displayed. And when I set the max_results to very high value, i get an error:

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as     
XML' in C:\xampp\htdocs\oauth\oauth.php:80 Stack trace: #0   
C:\xampp\htdocs\oauth\oauth.php(80): SimpleXMLElement->__construct('') #1 {main} thrown  
in C:\xampp\htdocs\oauth\oauth.php on line 80

Answer 1

The maximum amount you can get for a feed is 100. If you go above this then bad things happen. You can use startIndex in combination with the max-results to specify where you want to get from and how many at a time.

 # max-results - max is 100 entries
 # startIndex - Used for paging so you can get the next bunch of results

Check Google Contacts API for more information on the layout of the XML, information on what some of the other method you can use are, and language specific methods. Try looking at the Retrieving contacts using query parameters and Retrieving all contacts sections for what you need here.
