如何在PHP中回显解密数据

Question

First, i have use aes_encrypt to encrypt the password

Then i have use aes_decrypt to decrypt the password

The issue is when i try to echo out the data in a table using <?php echo $row['pass'];?>, there'll be an error

"Undefined index: pass in"

SQL insert

insert into username (userName,pass) values('$userName', aes_encrypt('$pass','k'))

SQL select

SELECT UserNameID,userName,aes_decrypt(pass,'k') from username

What went wrong?

Answer 1

Don't you need to use an alias here?

SELECT aes_decrypt(pass, 'k') AS pass_decrypted FROM ...

And then access it with

echo $row['pass_decrypted'];
