We have released another update of the PHP Sample Code, version 2.0.3

• Modified error handling from using "embed" requests to support XML response error paths
• Added function to delete cached thumbnails easily
• Optimized code for generating request arguments and options in consolidated functions
• Fixed oversight that put &stwu (secret key) on embedded requests, which will be blocked eventually

Check the code documentation for details.

NOTE: It is highly recommended to upgrade from previous versions to optimize the request patterns. This can significantly reduce your bandwidth consumption in certain cases, like error requests and bad code situations.
