10 able to read files in it if you have cache option enabled

15 provided comments and project wiki page (links in README file)
16
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');
