问题描述

如何在mysqli prepare语句中执行以下操作?

How can I do the following in mysqli prepare statement?

$result = mysql_query($sql);
$data = mysql_fetch_assoc($result);
return $data:

推荐答案

在某些地方创建与mysql的连接之后，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');
?>

当您需要执行查询或执行其他操作时，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(如果您有一个类，可以编写一个析构函数)，如果不再需要它，则应关闭与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();
?>

您可以对拥有的结果对象做更多的事情. 因此，请在此处详细了解MySQLi_Result:

You can do much more with the result object you have. So read more about the MySQLi_Result here:
