PHP Updatable Variable : <p>I am working on a site that has a variable for the current year. This variable is used throughout the website. The variable needs to be manually updated every year in the middle of the summer. I want to allow the admin to update that variable but it seems wasteful to create an entire table for one value.</p>

<p>The site is written in php and so I was wondering, is there anyway to update a variable with PHP through a form or something like that?</p>
