Getting the next number in php : <p>I'm not sure what the easiest way to go about this is, I just want one button on a page called assign.</p>

<p>When you visit the page, it says 001, once you click assign, the page refreshes and it says 002 and so on. Do I need a DB to keep track of the current number? </p>

<p>Is there an easier way to do this with javascript that does not need a DB?</p>
