<?php $password = '1234567'; $salt = '84870' $password = sha1($pwd.$userinfo['salt'].config('pwd_str')) var_dump($password); ?>

There is a syntax error in the code. It should be:

<?php
$password = '1234567';
$salt = '84870';
$password = sha1($password.$salt.config('pwd_str'));
var_dump($password);
?>

The `sha1()` function is used to hash the password concatenated with the salt and a configuration string. The result is then assigned to the `$password` variable and printed using the `var_dump()` function.

if($userinfo['pwd'] != sha1($pwd.$userinfo['salt'].config('pwd_str')))

{ // password does not match, return error message

return "Incorrect password.";

}

else

{

// password matches, continue with login process

}

if($userinfo['pwd'] != sha1($pwd.$userinfo['salt'].config('pwd_str')))什么意思

这段代码的意思是：如果用户输入的密码和存储在数据库中的密码不相等，则不通过验证。密码在数据库中可能已经使用了哈希函数和盐值进行了加密，因此需要重新计算哈希值以检查密码是否正确。如果密码正确，则登录授权成功。
