TCPDF: open-source PHP class used to generate PDF documents

To add the PDF document generation function to the PHP project, the open-source class library TCPDF is undoubtedly the best choice. I personally feel that its biggest advantage is that it can directly use HTML-style strings to generate PDF, that is, it can determine the style and content of the document through HTML, and then export the PDF file with TCPDF. The official website of TCPDF is as follows: www.tcpdf.org download

After reading 65 examples provided by TCPDF, you can fully master its usage. You can perform the following five steps:

1. require_once import the tcpdf. php file and the corresponding language of the config/lang/directory

2. instantiate TCPDF

3. Set the format of a PDF document, including the document information, header, footer, Font, outer spacing, image border, and paging.

4. The content of the imported PDF document can be a single line or multiple lines of simple strings, or HTML strings.

5. output PDF document

TCPDF open-source projects are very active. Basically, new versions of TCPDF packages will be released every few days. Therefore, new bugs are generally handled in a short time. I have discovered a bug in HTML color parsing. after submitting the bug, I solved it in the new version released the next day.
