How to Create a PDF file with PHP

This tutorial we will learn how to use PDF in PHP, so this PDF we can use as virtual document, so if you want to build a payment system you can send invoice order in the form of PDF to look more professional. there are lots of packages to help us create PDFs. one of them is TCPDF. How to use and its implementation, we just start this tutorial.

What Will I Learn?

• Installation TCPDF
• Setting PDF in PHP
• Add Document Information
• Styling PDF

Requirements

• Php >= 5.6
• Composer
• Localhost (xampp,wampp, or etc)
• Basic php

Difficulty

• Basic

Install and Preparation

The first step we have to download the first package tcpdf, we can download it from https://packagist.org/packages/tecnickcom/tcpdf . and then you open the folder where you will start the project in this tutorial my folder is tcpdf and run command prompt in there.

composer require tecnickcom/tcpdf

package.json

{
    "require": {
        "tecnickcom/tcpdf": "^6.2"
    }
}

Use PDF in Php

After we finish the installation process. now we will start using TCPDF in PHP. I will create an index.php file which will use the existing functions in TCPDF.
index.php

Create New Documment

Well... to create PDF document I provide variable with name $pdf to initialize new TCPDF(). If you want to see what functions are provided by TCPDF, We can see it in vendor/tecnickcom/tcpdf/tcpdf.php .
$pdf = new TCPDF(PDF_PAGE_ORIENTATION,PDF_UNIT,PDF_PAGE_FORMAT, true, 'UTF-8',false);.

PDF_PAGE_ORIENTATION: $orientation (string) page orientation. Possible values are (case insensitive)

:P or Portrait (default)

L or Landscape

'' (empty string) for automatic orientation

PDF_UNIT $unit (string) User measure unit. Possible values are:

• pt: point
• mm: millimeter (default)
• cm: centimeter
• in: inch

A point equals 1/72 of inch, that is to say about 0.35 mm (an inch being 2.54 cm). This is a very common unit in typography; font sizes are expressed in that unit.

PDF_PAGE_FORMAT
$format (mixed) The format used for pages. It can be either: one of the string values specified at getPageSizeFromFormat() or an array of parameters specified at setPageFormat().

$unicode=true
$unicode (boolean) TRUE means that the input text is unicode (default = true)

'UTF-8'
$encoding (string) Charset encoding (used only when converting back html entities); default is UTF-8.

$pdfa=false
$pdfa (boolean) If TRUE set the document to PDF/A mode.

Functions in TCPDF

We will learn and understand the functions that we can use to create PDFs and organize PDF files
We can add information from the pdf document we created.

Add Document Information

$pdf->SetCreator('ANONYMOUS');
$pdf->SetTitle('Create PDF with PHP');
$pdf->SetSubject('TPDF TUTORIAL UTOPIAN');

$pdf->SetCreator('ANONYMOUS'); : $creator (string) The name of the creator.

$pdf->SetTitle('Create PDF with PHP'); :$title (string) The title of document PDF.

$pdf->SetSubject('TPDF TUTORIAL UTOPIAN');:$subject (string) The subject of document PDF.

$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
Defines the default monospaced font. * Hive account@param $font (string) Font name.

Set Margin

We will set the margin of the PDF we created with the following functions.

$pdf->SetMargins(PDF_MARGIN_LEFT,PDF_MARGIN_TOP,PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(true,PDF_MARGIN_BOTTOM);

$pdf->SetAutoPageBreak(true,PDF_MARGIN_BOTTOM);

Hive account@param $auto (boolean) Boolean indicating if mode should be on or off.

Hive account@param PDF_MARGIN_BOTTOM (float) Distance from the bottom of the page.

Scalling image

We can also scaling image with passing parameters as follows

$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);

Font Subsetting

$pdf->setFontSubsetting(true);
$pdf->SetFont('helvetica','',14,'',true);
$pdf->AddPage();

$pdf->setFontSubsetting(true);

Hive account@param $enable (boolean) if true enable font subsetting by default.

$pdf->SetFont('helvetica', ' ' , 14 , '' , true);

Hive account@param $family (string) Family font. It can be either a name defined by AddFont() or one of the standard Type1 families (case insensitive):

It is also possible to pass an empty string. In that case, the current family is retained.


Hive account@param $style (string) Font style. Possible values are (case insensitive):

• empty string: regular
• B: bold
• I: italic

• O: overline

or any combination. The default value is regular. Bold and italic styles do not apply to Symbol and ZapfDingbats basic fonts or other fonts when not defined.

Hive account@param $size (float) Font size in points. The default value is the current size. If no size has been specified since the beginning of the document, the value taken is 12.

Hive account@param $fontfile (string) The font definition file. By default, the name is built from the family and style, in lower case with no spaces.

Hive account@param $subset (mixed) if true embedd only a subset of the font (stores only the information related to the used characters); if false embedd full font; if 'default' uses the default value set using setFontSubsetting(). This option is valid only for TrueTypeUnicode fonts. If you want to enable users to change the document, set this parameter to false. If you subset the font, the person who receives your PDF would need to have your same font in order to make changes to your PDF. The file size of the PDF would also be smaller because you are embedding only part of a font.

Hive account@param $out (boolean) if true output the font size command, otherwise only set the font properties.

Add PDF file

Add Content PDF

$pdf->AddPage(); : To add all the settings we've made before

Result Code Tutorial

I share every part I describe one by one in each section, now I want to merge files and functions into one. all my code is only in one file that is index.php.

index.php

<?php 
require_once 'vendor/autoload.php';
define('K_PATH_IMAGES','images/');
//create new document
$pdf = new TCPDF(PDF_PAGE_ORIENTATION,PDF_UNIT,PDF_PAGE_FORMAT, true, 'UTF-8',false);
//document information
$pdf->SetCreator('ANONYMOUS');
$pdf->SetTitle('Create PDF with PHP');
$pdf->SetSubject('TPDF TUTORIAL UTOPIAN');
//header data
$pdf->SetHeaderData('utopian.jpg',30,'Tutorial Create PDF in Php with TCPDF', 'This is tutorial from Creator @alfarisi94',array(48,89,112));
$pdf->SetFooterData(array(0,0,0),array(0,0,0));
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN,'',PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_MAIN,'',PDF_FONT_SIZE_MAIN));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
//set margin
$pdf->SetMargins(PDF_MARGIN_LEFT,PDF_MARGIN_TOP,PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(true,PDF_MARGIN_BOTTOM);
//set scalling image
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
//font subsetting
$pdf->setFontSubsetting(true);
$pdf->SetFont('helvetica','',14,'',true);
$pdf->AddPage();
$html=<<<EOD
<h1>Thank you for following this tutorial</h1>
<p>I hope you get a lot of benefits in this tutorial, see you in the next tutorial in <span style="color:#ccccc;">utopian</span></p>
EOD;
$pdf->writeHTMLCell(0,0,'','',$html,0,1,0,true,'',true);
$pdf->Output('tutorial_PDF.pdf','I');

Run your localhost to your index.php. and we will see the pdf file we have created.

We finally managed to create a pdf file using PHP, many settings that we build to create a PDF file but after we managed to make its settting, we can use it repeatedly. just so much of me I hope you benefit from the tutorial I have created. Thank you for following this tutorial
