如何在PHP中回显解密数据

First, i have use aes_encrypt to encrypt the password

enter image description here

Then i have use aes_decrypt to decrypt the password

enter image description here

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?

    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'];

    In your result set is the password column named as used function. All you need is to set an alias of that column such as: aes_decrypt(pass,'k') as 'pass':

    SELECT UserNameID, userName, aes_decrypt(pass,'k') as pass FROM username
    

    Your PHP code expect the column 'pass' in result set..
