document pdf php portable use Revise Jianhe document

[php100 translation] The full name of PDF is Portable Document Format, which is translated as Portable Document Format. It is a portable document format launched by Adobe. PDF has the characteristics of being independent of the operating system, which makes it an ideal document format for electronic document distribution and digital information dissemination on the Internet. Today we will discuss how to create PDF documents using PHP and modify PDF using PHP.

To use PDF documents in PHP, we need to use the TCPDF package, a class used by PHP to read PDF.

Create PDF document with PHP

You can download the TCPDF package from the link given below.

TCPDF - PHP class for PDF: http://sourceforge.net/projects/tcpdf/files/

This is a free and easy-to-use plug-in package, Below we give some examples to demonstrate how to use the TCPDF package.

Example 1: Use PHP to generate a simple PDF document
