title: One time download liks in php?
body: <p>I am trying to create a one time download link in php as my client would like to sell bus trip tickets on their website. I am a begginer/ never really wrote my own php and I am trying to create a one time download link for the tickets. The issue is that the vouchers ae created dynamically by php too and a variable is stored in the link, otherwise I could just use the builtin function of my cms. However, I want to create one time link to a page redirecting people to the page with the redirect.</p>
  
  <p>If someone could outline the process of creating one time links that would be greatly apreciated, and if some could provide some example code that would be great.</p>
  
  <p>Thank you,
  Thomas</p>
