Solution 1:

That's not how forms work.

The browser will only send values of form controls (<input>, <select>, <textarea>) to the server. It won't send values of arbitrary named elements. (in fact, that name="a" is invalid HTML)

Instead, you should use an <input type="hidden" name="a" value="" />, and set the value attribute of this <input> tag to the value you want PHP to get.

Solution 2:

I guess, you want only to change the values in HTML elements. For that you need a XML parser (i.d). I think shamittimar's post may help you. He does exactly what you want.
