    $confirmpassword = $_POST['confirmpassword'];
            $value_check = true;
            $ciphering = "AES-128-CTR";
            $options = 0; 
            $encryption_iv = '1234567891011121'; 
            $encryption_key = "GeeksforGeeks";
            $confirmpasswordencryption = openssl_encrypt($confirmpassword, $ciphering,$encryption_key, $options, $encryption_iv);  

$encryption = "pABqPJhobIMHzqai"
                                                        $ciphering = "AES-128-CTR";
                                                        $options = 0;
                                                        $decryption_iv = '1234567891011121'; 
  
// Store the decryption key 
$decryption_key = "GeeksforGeeks"; 
  
// Use openssl_decrypt() function to decrypt the data 
$decryption=openssl_decrypt ($encryption, $ciphering,  
        $decryption_key, $options, $decryption_iv);

If you can use database,you could create a table to map a file to an id.

Create a 'mapping_table' 

id - integer
file_location - string

Your URL would look something like localhost/waterwell/e_book.php?id=12 .

make links that return to your server with querystring GET params identifying the file. the server can then do echo file_get_contents() after you figure out which file from the inputs

In your example it's trivial. simply omit the portion of the url you don't want shown and fill it back in on the server.
