Implementation of symmetric encryption algorithm in php

Recently, I suddenly wanted to save some confidential things in the database, and then I thought about how to prevent others from understanding what is stored even if they enter the database, so the only way is to encrypt it; but we still have to read it ourselves, so we can only Find some symmetric encryption algorithms and decrypt them when we want to see them. The following introduces the implementation of a simple symmetric encryption algorithm in PHP.
