Steps to make web content password protected in PHP

  1. Give a password box to the user so that user can input password to see the protected content
  2. Then pass the value of the password box using post method. ( I prefer this method because it will not show the password in the URL)
  3. Store the value in a PHP variable.
  4. Now add an “if else” condition to compare the password entered by the user with the original password.
  5. If the passwords are same then echo the Protected Content.
