How to generate the title and content of a txt file using php

This article describes in detail how php generates the title and content of a txt file. The following is a good example. The code is as follows:
/**
* 1. when a Buddy worked a few days ago, they asked him to write a file generation class: generate a file. the file types include txt, html, csv, pdf, doc (or docx ).
*
* 2. the generated content is a table (like a table in html). the parameter is the file type generated, the title of the generated content (array), and the generated content (array, corresponding to the title ).
