What software is composer?
Composer is a tool used to manage dependency relationships in PHP. It was proposed and implemented by Nils Adermann and Jordi Boggiano. The first version was released on March 1, 2012.
● We can declare the external tool libraries we depend on in the project, and Composer will help you install these dependent library files. With it, we can easily use one command to integrate other people’s excellent code Quote it into our project.
● Composer is not installed globally by default, but is installed based on a directory of a specified project (such as vendor).
● Composer requires PHP 5.3.2 or above, and openssl needs to be turned on.
● Composer can run on Windows, Linux and OSX platforms.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
