Follow these steps to generate PDFs in PHP

1. Install Composer

A composer is a tool for dependency management in PHP, that allows you to add/install the libraries and packages for your project and it will manage (install/update) them for you. Go to the download page download the Composer-Setup.exe, and get it installed on your machine. To verify the installation open the command prompt and type in “composer” You will see the version and other information.

2. Install mPDF Library

For generating PDFs using PHP, Composer is required because we are going to use mPDF which is a PHP library that will be installed via Composer. So go to your project folder, open the command prompt & hit the command given below, this will install the mPDF library.

composer require mpdf/mpdf

3. Create files & folders

So we are ready to generate PDF in PHP, before that we need to create files & folders and create the highlighted files in your project directory as per the given screenshot. Vendor folder, composer.json & composer. lock file will be created automatically when you complete step-2.

Let me just walk you through these files and folders:

“docs” is the folder to store the generated PDF
index.php is the main file that will display the UI screen to generate pdf on button click.
script.php file will contain the business logic to create a pdf in PHP
style.css file contains the CSS to style the PDF

4. Write the code

So we have created the files and folder, and after that update your files with the code given below.

index.php

<html lang="en">

5. Run It!!

Since we have completed writing the code, and now it is time to see what our changes look like. So save all files and after that open the project in your local host. In my case it is http://localhost/projects/codingbirds_/generate-pdfs-in-php.

Here is the output screenshot that looks like.

When you click, it will generate PDF and save in a folder(docs).
