title: How to make a secure web links with PHP?
body: <p>I am developing an web application with raw PHP for a school. When an user visits a student's profile page the web link on the address bar shows like this- <a href="http://localhost/utc/studentprofile.php?studentid=11100103" rel="nofollow">http://localhost/utc/studentprofile.php?studentid=11100103</a>. But I want to appear it like this- <a href="http://localhost/utc/studentprofile.php?studentid=.I1vlXKbsAAljiXXX4ylPpWER1D8re93AA--" rel="nofollow">http://localhost/utc/studentprofile.php?studentid=.I1vlXKbsAAljiXXX4ylPpWER1D8re93AA--</a> </p>
  
  <p>I can do it using base64_encode but if I do when the user tries to view the student's profile, it doesn't show any information.</p>
  
  <p>Would anyone please kindly help me on how to do this?</p>
  
  <p>Thanks in Advance</p>
