title: Random array output into href
body: <p>I am very new to PHP and kinda new to HTML.
  I am making a website with a product of the week and have an idea but can't find out how to perform it.</p>
  
  <p>My idea is to create and array with every different product and use array_rand to randomly choose one, then use a cron job to run it every Monday.
  I then wish for the chosen array output to be put into the href within the button for the product of the week.</p>
  
  <p>Am I going about this correctly or am I being horrifically stupid? </p>
  
  <p>Cheers, Fynn</p>
