Installation with Composer

If you're using Composer to manage dependencies, you can use

$ composer require arimac/fpdf:^1.8

or you can include the following in your composer.json file:

{
    "require": {
        "arimac/fpdf": "^1.8"
    }
}

Usage

• To download a file as a stream

<?php
require('fpdf.php');

$pdf = new FPDF();
$pdf->StartDownload('sales_report.pdf');
for($i=0; $i<100000; $i++) {
  $pdf->AddPage();
  $pdf->SetFont('Arial','B',16);
  $pdf->Cell(40,10,'Hello World!');
}
$pdf->Close();

Now FPDF will sending the generated data to the browser without waiting to finish the loop.

• To present a preview of a file as stream

require('fpdf.php');

$pdf = new FPDF();
$pdf->StartPreview('sales_report.pdf');

  $pdf->AddPage();
  $pdf->SetFont('Arial','B',16);
  $pdf->Cell(40,10,'Hello World!');
}
$pdf->Close();
