You should write a php page accepting the JSON using post and save it to database.

In javascript when you are ready to save the JSON, send the JSON to the PHP page using AJAX. This is the way to save some client side data without using forms.

As explained in this answer

or if its a form you can refer this answer to submit the serialised data with HTML form

$.get('file.php?var='+variable);

Then in PHP $_GET['var'];
