Steps to make web content password protected in PHP

Below are the steps to perform our task:

  1. Give a password box to the user so that the user can input a password to see the protected content.
  2. Then pass the value of the password box using the post method with an HTML form. ( I prefer this method because it will not show the password in the URL as query string)
  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 password matches then display the Protected Content using the PHP echo.
