[DOCKER] [PHP] A story about outputting PDF with TCPDF + FPDI

Introduction

As the title says I tried to output PDF using the ** TCPDF ** and ** FPDI ** libraries. This time I will execute it from the command line.

Main story

Environment

Please prepare an environment where PHP and Composer can be used as you like.

Docker The Docker environment I used this time is as follows (partially omitted).

yml:./docker-compose.yml

version: '3'
services:
 php:
   build: ./php
   volumes:
     - ./work:/home/work

./php/dockerfile

FROM php:7.3-fpm
COPY php.ini /usr/local/etc/php/

# Composer
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" \
  && php -r "if (hash_file('sha384', 'composer-setup.php') === '795f976fe0ebd8b75f26a6dd68f78fd3453ce79f32ecb33e7fd087d39bfeb978342fb73ac986cd4f54edd0dc902601dc') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" \
  && php composer-setup.php \
  && php -r "unlink('composer-setup.php');" \
  && mv composer.phar /usr/local/bin/composer

ini:./php/php.ini

date.timezone = "Asia/Tokyo"

Composer When the launch is complete, enter the php container and Install the library in Composer.

In addition to the library, the description of autoload is also added.

/home/work/src/composer.json

{
    "require": {
        "setasign/fpdi": "^2.3",
        "tecnickcom/tcpdf": "^6.3"
    },

    "autoload": {
        "psr-4": {
            "Classes\\" : "classes/"
        }
    }
}

Once the installation is complete, you're done.

# cd /home/work/src
# composer install

Implementation

file organization

# cd /home/work/

# ls /home/work/output/pdf/fileYYYYmmdd-HHiiss #PDF output file
# ls /home/work/src/resources/font/ipam.ttf #Font storage location
# ls /home/work/src/resources/pdf/templete.pdf #PDF template storage location
# ls /home/work/bin/make-pdf.php #Source to run on the command line
# ls /home/work/src/bootstrap.php #Start-up file(Omitted)

# ls /home/work/src/classes/common/DynamicProperty.php #Dynamic class(Omitted)
# ls /home/work/src/classes/MyTcpdf/FontColor.php #Font color class(Omitted)

template

It's a very simple PDF template file.

Source

/home/work/bin/make-pdf.php

<?php

require_once __DIR__ . '/../src/bootstrap.php';

use Classes\MyTcpdf;
use Classes\MyTcpdf\FontColor;

//Output without using a template
$myTcpdf = new MyTcpdf();
$myTcpdf->addPage();
$myTcpdf->setText('Output without using a template', 10, 20, new FontColor(0, 255, 0));
$myTcpdf->outputPdfFile();

//Output using template
$myTcpdfTmp = new MyTcpdf();
$myTcpdfTmp->addPageWithTemplete(1);
$myTcpdfTmp->setText('Output using template', 10, 20, new FontColor(255, 0, 0));
$myTcpdfTmp->outputPdfFile();

        $page = $this->fpdi->importPage($_pageNum);
        $this->fpdi->AddPage();
        $this->fpdi->useTemplate($page, null, null, null, null, true);
    }

    /**
     *PDF file output
     */
    public function outputPdfFile()
    {
        $this->fpdi->Output(
            $this->getOutputFilename(),
            self::OUTPUT_FORMAT_CHAR
        );
    }
}

Execution command

php /home/work/bin/make-pdf.php

Execution result

The file was output as follows.

No template	There is a template

At the end

Since you can output characters on the PDF template, you can output only the necessary information without changing the format. It seems that it can be used for files such as rosters, invoices, receipts, etc. where only specific parts change.
