Hi @Goldmine,
All new access tokens are short lived (~4 hours typically). As you found out, refresh token can be used to achieve long term access. You can generate such token by hand using procedure like the one, described here. Checked and working. 😉

You need to integrate in your php code only the last step, described there (i.e. the refresh step). You have to keep track for the expiration moment (calculated as refresh moment plus "expires_in" time), for every single access token, and when current time passes this expiration moment and you need to perform some API call, refresh the access token as described. It's easier instead of using access token as constant to implement accessor function and use it whenever you're using your token at present, so will be able track the needed refresh moment.
Hope this helps.
