PHP implementation: How to generate a QR code business card with company information?

With the rapid development of mobile Internet, the application of QR codes is becoming more and more widespread. In business communications, traditional paper business cards are often not convenient enough, and QR code business cards have become a more convenient and environmentally friendly choice. This article will introduce how to use PHP to generate QR code business cards with company information, and attach code examples to help readers better understand the implementation method.

First of all, we need to understand the basic QR code generation principle. In PHP, you can use the third-party library QRcode for PHP to generate QR codes. QRcode for PHP is an open source library that is simple and convenient to use and can generate high-quality QR codes.

The following is a simple code example showing how to use QRcode for PHP to generate a basic QR code:

The above code will generate a file named qrcode.png## The QR code image of # has the content "Hello, World!". QRcode::pngThe function is responsible for generating a QR code. The first parameter is the content of the QR code to be generated. The second parameter is the file name to save the generated QR code image. The third parameter is is the error correction level, and the fourth parameter is the size of the QR code.

 "ABC公司",
    "address" => "北京市朝阳区",
    "tel" => "010-12345678",
    "email" => "info@abc.com"
);

$text = json_encode($companyInfo);
$filename = "qrcode.png";

QRcode::png($text, $filename, QR_ECLEVEL_M, 5);
echo "二维码生成成功！";
?>

$companyInfo, which stores information such as company name, address, phone number, and email address. Use the json_encode() function to convert the array into a string in JSON format, and then generate the string as the content of the QR code.

 "ABC公司",
    "address" => "北京市朝阳区",
    "tel" => "010-12345678",
    "email" => "info@abc.com"
);

$text = json_encode($companyInfo);
$filename = "qrcode.png";

QRcode::png($text, $filename, QR_ECLEVEL_M, 5);

// 加载二维码图片
$qrCode = imagecreatefrompng($filename);

// 加载背景图片
$bgImage = imagecreatefromjpeg("bg.jpg");

// 将二维码图片叠加在背景图片上
imagecopymerge($bgImage, $qrCode, 100, 100, 0, 0, imagesx($qrCode), imagesy($qrCode), 100);

// 添加公司Logo
$logoImage = imagecreatefrompng("logo.png");
imagecopymerge($bgImage, $logoImage, 150, 150, 0, 0, imagesx($logoImage), imagesy($logoImage), 100);

// 输出处理后的图片
imagejpeg($bgImage, "final_qrcode.jpg");

echo "二维码生成成功！";

imagedestroy($qrCode);
imagedestroy($bgImage);
imagedestroy($logoImage);
?>

imagecopymerge function to superimpose the QR code image on the background image and add the company Logo added to background image. Finally, the processed image is output through the imagejpeg function.
