I've a question how can I do an AJAX request to a DB, in which I store tags, for example (DB):

ID | tag_name
1 | php
2 | mysql
etc.

and then to populate this results into : availableTags: ["tag1", "tag2", "tag3"];

the script :

$(document).ready(function(){
    $("#mytags").addtags({
        availableTags: ["tag1", "tag2", "tag3"]
    });
});

EDIT:

My question is exactly how to render the results and put any of the tags names into separate brackets and they should be coma separated like this : ["tag1","tag2" etc.]

Make a file that gets you the needed return on request.
Do an AJAX request as described in the jquery manual*
....
profit!

*code:

$.ajax({
  url: "yourURL.php",
  context: document.body,
  success: function(){
    //DO YOUR STUFF HERE. Probably something with the tags and all
  }
});
