Solution to the problem of garbled text content in PHP reading txt text

First of all, let’s talk about the encoding format of txt file ANSI, Unicode, UTF-8, Unicode Big Endian, generally the default is ANSI. Directly using PHP to read will definitely cause garbled code, because the web page encoding is generally UTF-8 or GB2312.

After reading many solutions from masters, I feel it is too complicated. In fact, if it is not commonly used, you only need to use Editplus software to re-encode the txt text you want to read.
