  17 == QUICK START ==
  18
  19 Notice: probably you should'nt use all of this in same script :)
  20
  21 <?php
  22
  23 //include only that one, rest required files will be included from it
  24 include "qrlib.php"
  25
  26 //write code into file, Error corection lecer is lowest, L (one form: L,M,Q,H)
  27 //each code square will be 4x4 pixels (4x zoom)
  28 //code will have 2 code squares white boundary around
  29
  30 QRcode::png('PHP QR Code :)', 'test.png', 'L', 4, 2);
  31
  32 //same as above but outputs file directly into browser (with appr. header etc.)
  33 //all other settings are default
  34 //WARNING! it should be FIRST and ONLY output generated by script, otherwise
  35 //rest of output will land inside PNG binary, breaking it for sure
  36 QRcode::png('PHP QR Code :)');
  37
  38 //show benchmark
  39 QRtools::timeBenchmark();
  40
  41 //rebuild cache
  42 QRtools::buildCache();
  43
  44 //code generated in text mode - as a binary table
  45 //then displayed out as HTML using Unicode block building chars :)
  46 $tab = $qr->encode('PHP QR Code :)');
  47 QRspec::debug($tab, true);

  49 == TCPDF INTEGRATION ==
  50
  51 Inside bindings/tcpdf you will find slightly modified 2dbarcodes.php.
  52 Instal phpqrcode liblaty inside tcpdf folder, then overwrite (or merge)
  53 2dbarcodes.php
  54
  55 Then use similar as example #50 from TCPDF examples:
  56
  57 <?php
  58
  59 $style = array(
  60     'border' => true,
  61     'padding' => 4,
  62     'fgcolor' => array(0,0,0),
  63     'bgcolor' => false, //array(255,255,255)
  64 );
  65
  66 //code name: QR, specify error correction level after semicolon (L,M,Q,H)
  67 $pdf->write2DBarcode('PHP QR Code :)', 'QR,L', '', '', 30, 30, $style, 'N');
