How to solve the simple and traditional conversion of php

Hello, everyone! I have some database content that needs to be searched, but the Chinese content in it is both simplified and traditional. if you search directly using the content entered by the user, it will inevitably be omitted, therefore, I want to convert the search characters entered by the user. for example, if the simplified one is converted to the traditional one, the traditional one is converted to the simplified one, and then the two types of content can be searched together, in this way, php's simplified and traditional conversion will not be left behind.

However, I searched the internet and did not find any new simple and practical things. do you have any good solutions? For example, a function or something? It is also worth mentioning that all of my data content is UTF-8 encoded. do you know if this is the case?

Thank you!
