1.下载phpqrcode类库,地址:https://sourceforge.net/projects/phpqrcode/?source=typ_redirect
2.开启gd库
3.可以生成二维码了
<?phpnamespace Home\Controller;//use Org\Util\QRcode;use Think\Controller;include (‘phpqrcode.php‘);class IndexController extends Controller { ???public function index(){ ???????$str=‘helloword‘; ???????QRcode::png($str); ???}}
4.如果想在二维码中间介入图片的话,使用下面的方法
include ‘phpqrcode.php‘; $value = ‘http://www.jb51.net‘; //二维码内容 $errorCorrectionLevel = ‘L‘;//容错级别 $matrixPointSize = 6;//生成图片大小 //生成二维码图片 QRcode::png($value, ‘qrcode.png‘, $errorCorrectionLevel, $matrixPointSize, 2); $logo = ‘logo.png‘;//准备好的logo图片 $QR = ‘qrcode.png‘;//已经生成的原始二维码图 ??if ($logo !== FALSE) { ?$QR = imagecreatefromstring(file_get_contents($QR)); ?$logo = imagecreatefromstring(file_get_contents($logo)); ?$QR_width = imagesx($QR);//二维码图片宽度 ?$QR_height = imagesy($QR);//二维码图片高度 ?$logo_width = imagesx($logo);//logo图片宽度 ?$logo_height = imagesy($logo);//logo图片高度 ?$logo_qr_width = $QR_width / 5; ?$scale = $logo_width/$logo_qr_width; ?$logo_qr_height = $logo_height/$scale; ?$from_width = ($QR_width - $logo_qr_width) / 2; ?//重新组合图片并调整大小 ?imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, ?$logo_qr_height, $logo_width, $logo_height); } //输出图片 imagepng($QR, ‘helloweba.png‘); echo ‘<img src="helloweba.png">‘;
