THINKPHP5 generate QR code to display in template

THINKPHP5 generate two-dimensional code

1. Using the PHP QRCode class library
   Composer require Endroid/qrcode import Phpqrcode class Library

2. Class Library use
A $qrCode = new \endroid\qrcode\qrcode ();//instantiation

b Set up the parameters generated by the generation of the QR code

C Parameter resolution:
$setVersion = $qrCode setversion (5);//37*37
Set the version number, QR code symbol a total of 40 specifications of the Matrix, from 21x21 (version 1), to 177x177 (version 40), each version of the symbol than the previous version of the addition of 4 modules per side.

$setErrorCorrection = $qrCode seterrorcorrection (2);//Fault tolerance level, 2 fault tolerance rate: 30%
Fault tolerance level: 0:15%,1:7%,2:30%,3:25%

$setModuleSize = $qrCode setmodulesize (2);//Set the QR code module size

$setImageType = $qrCode setimagetype (' png ');//set QR code save type

$logo = ' uploads/accountpictrue/logo1.jpg ';//logo pictures
$setLogo = $qrCode, Setlogo ($logo);//Picture in the middle of QR code

$setLogoSize = $qrCode setlogosize (360);//Set logo size

$value = ' https://www.dongtianjr.com '; Two-dimensional code content
$setText = $qrCode SetText ($value);//Set Text to hide the QR code.

$setSize = $qrCode setSize (1024);//size after the generation of the QR code

$setPadding = $qrCode setpadding (48);//Set the border width of the QR code, default 16

$setDrawQuietZone = $qrCode Setdrawquietzone (true);//Set module spacing

$setDrawBorder = $qrCode Setdrawborder (true);//to the QR code plus a border ...
$text = ' xx sales, XX company! one or two ';
$setLabel = $qrCode-SetLabel ($text);//Add text underneath the generated picture

$setLabelFontSize = $qrCode setlabelfontsize (39);//generated text size,

$lablePath = ' uploads/qr/qr. TTF ';
$setLabelFontPath = $qrCode-Setlabelfontpath ($lablePath);//Set Label font

$color _foreground = [' r ' = + 108, ' g ' = = 182, ' b ' = = 229, ' a ' and ' = 0];
$setForegroundColor = $qrCode Setforegroundcolor ($color _foreground);//The color of the generated QR code

$color _background = [' r ' = + 213, ' g ' = = 241, ' b ' = = 251, ' a ' and ' = 0];
$setBackgroundColor = $qrCode-SetBackgroundColor ($color _background);//generated picture background color

$flieName = ' liukelk.jpg ';//two-dimensional code name

Save ($flieName) $qrCode;//Generate two-dimensional code

Note: If the label is garbled in Chinese, the Chinese font can be introduced.
