本文实例讲述了Laravel使用PHPQRCODE实现生成带有LOGO的二维码图片功能。分享给大家供大家参考，具体如下：

/**
* 利用phpqrcode来实现生成带有logo的二维码图片
*/
public function getQrCode(Request $request){
 $type = $request->input('type');//传递的类型 ios | android
 require_once(dirname(__FILE__) . '/phpqrcode/' . 'phpqrcode.php');
 $errorCorrectionLevel = 'H'; // 错误校正
 $matrixPointSize = 5; // 边界空白位置
 $QRcode = new \QRcode;
 if($type){
 if($type == 'ios'){
 $value = 'http://www.ios.com'; // 二维码存放的内容
 $QRcode->png($value, 'ios.png', $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
 //echo "二维码已生成";
 $logo = 'logo.png';//logo的图片地址
 //echo " <img src='../../../public/logo.png'>";
 $QR = 'ios.png'; //二维码图片地址
 //echo " <img src='../../../ios.png'>";
 if($logo !== FALSE){
 $QR = imagecreatefromstring(file_get_contents($QR));
 $logo = imagecreatefromstring(file_get_contents($logo));
 $QR_width = imagesx($QR);
 $QR_height = imagesy($QR);
 $logo_width = imagesx($logo);
 $logo_height = imagesy($logo);
 $logo_qr_width = $QR_width / 5;
 $scale = $logo_width / $logo_qr_width;
 $logo_qr_height = $logo_height / $scale;
 $from_width = ($QR_width - $logo_qr_width) / 2;
 imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
 }
 imagepng($QR,'ios.png'); //跟logo合并之后的地址
 $a = 'http://www.ios.com/ios.png';
 $status = 0;
 $msg = $a;
 }elseif($type == 'android'){
 $value = 'http://www.android.com'; // 二维码存放的内容
 //var_dump($value);
 $QRcode->png($value, 'android.png', $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
 //echo "二维码已生成";
 $logo = 'logo.png';//logo的图片地址
 //echo " <img src='../../../public/logo.png'>";
 $QR = 'android.png'; //二维码图片地址
 //echo " <img src='../../../android.png'>";
 if($logo !== FALSE){
 $QR = imagecreatefromstring(file_get_contents($QR));
 $logo = imagecreatefromstring(file_get_contents($logo));
 $QR_width = imagesx($QR);
 $QR_height = imagesy($QR);
 $logo_width = imagesx($logo);
 $logo_height = imagesy($logo);
 $logo_qr_width = $QR_width / 5;
 $scale = $logo_width / $logo_qr_width;
 $logo_qr_height = $logo_height / $scale;
 $from_width = ($QR_width - $logo_qr_width) / 2;
 imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
 }
 imagepng($QR,'android.png'); //跟logo合并之后的地址
 $a = 'http://www.android.com/android.png';
 $status = 0;
 $msg = $a;
 }else{
 $status = 1;
 $msg = '没有该类型！';
 }
 //QRcode::png($value, 'sunny.png', $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
 }else{
 $status = 2;
 $msg = '参数传递不完整！';
 }
 return response()->json(['status' => $status,'msg' => $msg])->header('Access-Control-Allow-Origin', '*');
}
