$inputPassword = substr($inputPassword, 8);
$newPassword .= crypt($encryptString, "HIDDENSALT");
crypt_password_input($inputPassword, $newPassword);

推荐答案
你在这个条件块下没有 return 语句.我已经在那里添加了返回.
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);
}
