It is normal to add an email address to the database. The email address is a special form. We often need to verify it before adding it. When we need to verify whether the email address is valid, this library just comes into play.

Array sorting is also often encountered in development. When paging, we usually fetch data from the database and put it into an array to display during page traversal. At this time, you can sort according to your own ideas. This class library is It can come in handy.

In our actual development, we need to use many data formats. Arrays are also a very common one. Of course, merging arrays becomes very time-consuming. This class library can help you save a lot of time in handwriting.
