Online php form (inserts) in pdf form and send via email

Question

So first hello all.
There are 4 PDF Forms amd 4 php forms on a website.
The user should be able to fill out the php form, click on send and the inserts from the user should be stored in the pdf form and send to an email adress.
I know that there are 3rd party tools, the convert it to a image, draw the inserts and convert it back.
But i want to know, how to do it with acrobat itself.
Is there any way to put varaibles in the pdf where php can set (fill)
If this is impossible:
I have heard, that there is a server version from acrobat who can manage this.
The information about this is rarly like i dont understand how much the costs are.
First : price x (for the server software itself)   
Second: price y (for every processed document)
Many thanks in advance

You cannot use Acrobat on a server in that manner. Acrobat is licensed for one user one system at a time.
You can create and FDF file with the form field data and use that data to fill-in a PDF. You needd to create a unique PDF that could be added to an email and then deleted. You could also accumulate the data in a database.
