This is a reminder that starting from January 1, 2015, new releases of the ads PHP client library will only support PHP 5.3 or later versions. This will allow us to implement namespacing and autoloading, which aren’t available in PHP 5.2. Please see our original blog post announcement for more information. If you have any questions about this, feel free to drop us a line on the DFP API forums, AdWords API forums, or Ads Developer Google+ page.
