PHP parser

You need to write a script in PHP that will accept requests with data from another server in XML format.
on the basis of this data, it will also form an answer in XML, fill the template with data from the request, attach a PDF file to the answer, as well as all these data received from the request and generated by the script itself will need to be written to MySQL.

I am ready to send a more detailed TK.

Deadlines are very burning.
