检查 mysqli_query 是否返回任何值?

I have the following code and I would like to know if mysqli_query returned any rows and if so return an error.

$result = mysqli_query($connection, "SELECT * FROM users");
    
if ($result == "") {
    echo "No records found";
} else {
    echo "There is at least one record in the database";
}

如果结果返回为空，我就会遇到麻烦.我已经尝试使用了几种东西，但如果没有找到任何东西，我无法弄清楚如何让它正常工作.
