推荐答案
在某处创建到 mysql 的连接后，这很简单:
That's pretty simple after you've created the connection to mysql somewhere:
<?php
// create the connection to mysql.
$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'my_db');
?>
当你需要做查询或做其他事情时引用 mysqli 对象.
The refer to the mysqli object when you need to do a query or do something else.
<?php
// get the result object.
$result = $mysqli->query($sql);
// fetch the result row.
$data = $result->fetch_assoc();
return $data;
?>
然后在某个时候(如果你有一个类，你可以写一个析构函数)如果你不再需要它，你应该关闭与 mysql 的连接.
Then at some point (if you have a class, you can write a destructor) you should close the connection to mysql if you won't need it anymore.
<?php
$mysqli->kill($mysqli->thread_id);
$mysqli->close();
?>
你可以用你拥有的结果对象做更多的事情.因此，请在此处阅读有关 MySQLi_Result 的更多信息:
You can do much more with the result object you have.
