PHP function not returning value

Question

For some reason I can not get my function to return a string...

$password = crypt_password_input($password, \"\");

//Encrypt Password longer than 8 characters
f         


        

Answer 1

you have no return statement under this condition block. i have added return there.

if($passwordLength > 8)
{
    $encryptString = substr($inputPassword, 0, 8);
    $inputPassword = substr($inputPassword, 8);
    $newPassword .= crypt($encryptString, "HIDDENSALT");
    return crypt_password_input($inputPassword, $newPassword);
}

Answer 2

I am not sure about your logic, but your code should be like this:

$password = crypt_password_input($password, "");

//Encrypt Password longer than 8 characters
function crypt_password_input($inputPassword, $newPassword)
{
    $passwordLength = strlen($inputPassword);

    if($passwordLength > 8)
    {
        $encryptString = substr($inputPassword, 0, 8);
        $inputPassword = substr($inputPassword, 8);
        $newPassword .= crypt($encryptString, "HIDDENSALT");
        return crypt_password_input($inputPassword, $newPassword);
    }
    else
    {
        $newPassword .= crypt($inputPassword, "HIDDENSALT");
        echo "Final: " . $newPassword . "<br/>";
        return $newPassword;
    }
}


echo "Encrypted from the input: " . $password . "<br/>";

In your code, you are recursively calling the input but not returning anything, so it fails if you have password longer than 8 characters.
