Hello everyone,
I am new to Thunkable but have created a complete with AppInventor. The simple question is how to call .php files running on a server and handling a MYSQL DB. I would be very thankful for a complete example of blocks showing the entire mechanism. One remark is that I cannot seem to find in my Thunkable Pro the call “from Web_API1 SET URL” command.
Thankful for any answer.

Hi @pmginvestda6z, welcome to Thunkable! 
Be sure to check out our posts about How to ask Great Questions v2.0 and our Community Guidelines as you get started.
Just doing a quick search here of the same keywords, I found this post from not long about running a php script on a server that pulls data from a MySQL database. I would suggest starting here.

As for the block for setting the URL, that is part of our Web API blocks. I will link to the docs for those here:
You can also set the URL by clicking on the gear icon for the Web API you’ve added in the advanced blocks drawer and add it in there.
