无法在多维数组中回显字符串但可以print_r

I've run into a weird problem, I can print_r() my variable and it produces the following:

print_r($_SESSION['userdata']);

outputs: Array ( [0] => Array ( [id] => 1 [username] => admin [firstname] => carl [lastname] => wirkus [password] => password [admin] => 1 [staff] => 0 [tenant] => 0 [email] => test@test.com ) 

However when I try to echo the username with:

echo "You are currently logged in as: " . $_SESSION['userdata']['username'] . "<br>";

outputs: You are currently logged in as: 

What have I done wrong?

    Looks closer at your print_r($_SESSION['userdata']);. It's an array inside of an array. So you're not going deep enough to reach your values.

    echo "You are currently logged in as: " . $_SESSION['userdata'][0]['username'] . "<br>";
