Continuing the discussion from About TalerPHP:
Hi @miro, welcome to TALER ICH. This category is not public yet, only available to you and your group (@i.php). You may invite other contributors if you like, and edit the post linked above which describes the TALER Integrations > TalerPHP category. Be careful with the first line that shows in TALER Integrations 
Do not hesitate to ask anything, modify the category description to your liking, etc. You may for example link to the code repository and describe the plan. Feel free to see what others have done.
TALER Integrations > Dolibarr is the only PHP integration project so far coming from the open calls, and I expect they will be using your code! You will surely be interested in cherry-picking from the TALER Integrations > WooCommerce code as well, which has already made some working Taler integration.
Happy hacking!
