Efficient control @User analysis: Limit the number of people and times of Aite

How to avoid overloading the system or degrading the user experience when dealing with @user parsing is a key issue. This article will introduce methods to effectively control the number of Ait people and the number of resolutions.

Unrestricted parsing @ users may cause waste of system resources. Therefore, setting restrictions is crucial. We can use the limit parameter of the preg_replace function to control the number of replacements, thereby limiting the number of users who are called.

For example, to replace only the first 5 @ users, you can use the following code:

 $text = preg_replace('/@(\w )/', ' <a href="https://www.php.cn/link/c91b95cae675d1368cf88f9a3da58e01">@$1</a> ', $text, 5);

If you need to send a notification to the user who is Tout, you can use the preg_match_all function to match all @ users, and then select the first n from them for notification processing, thereby controlling the amount of notification sent and avoiding excessive resource consumption.

For example:

 preg_match_all('/@(\w )/', $text, $matches);
$users_to_notify = array_slice($matches[1], 0, 10); // Only the top 10 users are processed

Through the above methods, developers can effectively control the number of Aites and the number of resolutions resolved by @user to ensure system stability and good user experience.
