PHP如何生成二维码图片

在php图片如何生成我们开发过程中php图片如何生成，往往php图片如何生成我们会遇到将某个商品或者将某个活动生成一个二维码php图片如何生成，当用户扫描二维码时候，用户可以直接跳转到商品详细页面或者活动详情页面。那我们如何生成一个二维码图片呢，来，看这里哦php图片如何生成！！！

1.封装

代码篇：

function qrcodeLogo($url='',$logo='',$filepath,$level=3,$size=20){ Vendor('phpqrcode.phpqrcode');//引入PHPQrcode $Level =intval($level) ;//容错级别 $matrixPointSize = intval($size);//生成图片大小 //生成二维码图片 $object = new \QRcode(); $time = time(); $object::png($url, $filepath, $Level, $matrixPointSize, 2,true); $QR = $filepath; if ($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 $path = '/qrcode/logo/' . time() . rand(100, 999) . '_qrcode.png'; $result = imagepng($QR, '.'.$path); return $path;}

2.看这里我们来调用使用啊

代码篇（片段）：

foreach ($goods as $k => $v) { $url = 'http://m.test.com/tmpl/product_detail.html?goods_id=' . $v['goods_id'] . '&roomid=' . $v['apply_id'] . '&saletype=1'; $qrcode_path = "/qrcode/" . time() . rand(100, 999) . '_qrcode.png'; $path = qrcodeLogo($url, $v['goods_img'], './' . $qrcode_path, 8, 9); $goods[$k]['goods_code'] = 'http://test.tstmobile.com' . $path; if($v['tbUrl']!==''){ $url2 = $v['tbUrl']; $qrcode_path2 = "/qrcode/" . time() . rand(100, 999) . '_qrcode.png'; $path2 = qrcodeLogo($url2, $v['goods_img'], './' . $qrcode_path2, 8, 9); $goods[$k]['tao_goods_code'] = 'http://test.tstmobile.com' . $path2; }else{ $goods[$k]['tao_goods_code'] =''; } if($v['jdUrl']!==''){ $url3 = $v['jdUrl']; $qrcode_path3 = "/qrcode/" . time() . rand(100, 999) . '_qrcode.png'; $path3 = qrcodeLogo($url3, $v['goods_img'], './' . $qrcode_path3, 8, 9); $goods[$k]['dong_goods_code'] = 'http://test.tstmobile.com' . $path3; }else{ $goods[$k]['dong_goods_code'] =''; } if($v['jdUrl']!=='' || $v['tbUrl']!==''){ $url4 = 'https://m.test.com/tmpl/MobileZitiCtl/index.html?apply_id='.$v['apply_id'].'&goods_id='.$v['goods_id'].'&company_name='.$live['company_name'].'&address='.$live['address'].'&shop_id='.$live['gl_merchants_id']; $qrcode_path4 = "/qrcode/" . time() . rand(100, 999) . '_qrcode.png'; $path4 = qrcodeLogo($url4, $v['goods_img'], './' . $qrcode_path4, 8, 9); $goods[$k]['ti_goods_code'] = 'http://test.tstmobile.com' . $path4; }else{ $goods[$k]['ti_goods_code'] =''; } }
