About 5 years ago I ran into this page by James Cridland. It’s empty now, but at the time he was sharing a file that parsed Google’s XML feed for a calendar via PHP code. It was particularly useful to me since I work with WordPress, which is written in PHP. On Nov. 17th, 2014, Google deprecated the API that allowed the XML to be parsed in this way, and released a new API. At the time of this writing, James had not made any plans or attempts to replace the old file, and posted a notice that his code no longer worked.
Since I used James’s code for nearly 5 years with excellent results, I’ve decided to share my new version written for Google’s API v3. I have sent this to James and give him free reign to share and modify as he desires, but I thought I’d share it here, just in case he doesn’t want to bother with it anymore.
