As I said, normally you need to include the complete path to PHP, just using the PHP command is not enough.

I do urge you to contact the web host support on this, they will probably be able to tell you more.
I have to add that I am not an expert in running cron jobs, it is something I have set up on occasion, but not with this, so I cannot be sure that what you are attempting will work at all.
I do question why you are trying to do this, as I don't see the reason to run it as a cron job. You can submit the feed directly to Google. If that isn't enough for you, for example if you want to submit the text file that the component outputs, and have it updated regularly, all you need is something that will regularly ping the web address of the feed.
