How to effectively control the number of people and the number of resolutions when parsing @ users?

Efficient control @User analysis: limiting strategy for the number of people and times

When building social or collaborative platforms, the resolution and link conversion of @user functions are crucial. However, when users @ a large number of users at the same time, how to effectively control the number of resolutions and the number of users to avoid system performance bottlenecks and user experience declines has become a challenge for developers.

Unrestricted @user resolution may cause excessive consumption of system resources. Therefore, limiting the number of @ users and the number of resolutions is crucial.

An effective solution is to take advantage of PHP's preg_replace function. The limit parameter of this function controls the number of replacements, thereby limiting the number of users converted to links. For example, if you want to parse up to 5 @ users each time, set limit parameter to 5.

In addition, if the application needs to send notifications when the user is @, you can use the preg_match_all function to match all users who are @, and then only process the notifications sent by the first N users to avoid excessive system load.

Through the above methods, the number and times of @-user analysis can be effectively controlled to ensure system stability and good user experience.
