Is it possible to post a data that is in a list through PHP to a MySQL database

Is it possible to post a data that is in a list through PHP to a MySQL
database

I have a function which creates a calendar, I want to be able to click the
individual dates and save a task in the database table, my function is
currently outputting this in an unordered list with list tags. How can I
submit this through PHP? Would I need to wrap this around in a form and
then use $_POST as per submitting a form? Or is there another procedure?
Does anyone have any working examples?
Forgive my ignorance. Thanks in advance for any help.
This is the calendar class that I am using:
<?php

$this->naviHref = htmlentities($_SERVER['PHP_SELF']);
