Thinkphp3.2.3 Integration Phpqrcode Sample code sharing for generation of QR codes

Thinkphp does not have a QR code-related library, so we can integrate phpqrcode to achieve the function of generating QR code.

Download Phpqrcode

Integration into the thinkphp framework

Under "Thinkphp\library\vendor\", create a new directory Phpqrcode to extract the contents of the compressed package to this folder.

Call Phpqrcode to generate two-dimensional code

Add the following method under the Indexcontroller controller:

Public Function QRCode ($url = "www.baidu.com", $level =3, $size =4)    {              Vendor (' Phpqrcode.phpqrcode ');                            $errorCorrectionLevel =intval ($level);//Fault tolerance level               $matrixPointSize = Intval ($size);//Generate picture size              //generate QR code picture               $ Object = new \qrcode ();                            $object->png ($url, False, $errorCorrectionLevel, $matrixPointSize, 2);       }

Access: 127.0.0.1/index/qrcode to see the generated QR code.

Create a QR code with logo

Call Phpqrcode to generate a QR code, and then use PHP's image correlation function to add the logo image to the generated QR code image.

Include ' phpqrcode.php '; $value = ' http://www.cnblogs.com/txw1958/'; QR Code content $errorCorrectionLevel = ' L ';//fault tolerance level $matrixPointSize = 6;//Generate picture size//generate QR code picture qrcode::p ng ($value, ' qrcode.png   ', $errorCorrectionLevel, $matrixPointSize, 2); $logo = ' logo.png ';///Ready logo image $QR = ' qrcode.png ';//The original two-dimensional code figure already generated if ($logo!== FALSE) {$QR = Imagecreatefromstr       ING (file_get_contents ($QR));       $logo = imagecreatefromstring (file_get_contents ($logo));        $QR _width = Imagesx ($QR);//QR code image width $QR _height = Imagesy ($QR);//QR code image height $logo _width = imagesx ($logo);//logo Picture width       $logo _height = Imagesy ($logo),//logo picture height $logo _qr_width = $QR _width/5;       $scale = $logo _width/$logo _qr_width;       $logo _qr_height = $logo _height/$scale;       $from _width = ($QR _width-$logo _qr_width)/2; Regroup the picture and resize imagecopyresampled ($QR, $logo, $from _width, $from _width, 0, 0, $logo _qr_width, $logo _qr_height,   $logo _width, $logo _height); }//Output picture imagepng ($QR, 'Helloweixin.png '); Echo '  ';
