title: I need help adding 30 days to today's date using PHP
body: <p>I have a user system for my website. I need to make something that adds 30 days to todays date.</p>
  
  <p>UPDATE:
  I decided to go with an integer instead of a date.</p>
  
  <p>Here's what I did. I set things up so that when someone pays their bill it sets their "Days" value to (value) + 30 </p>
  
  <p>I made a cron job that takes away 1 day from every user's "Days".
  Obviously, I set the cron job to run once per day.</p>
