PHP generates an example of a QR code with a LOGO image based on phpqrcode, phpqrcodelogo

This article describes an example of PHP generating a QR code with a LOGO image based on phpqrcode. Share it with everyone for your reference. The details are as follows:

Here PHP uses phpqrcode to generate a QR code with a LOGO image, which is very convenient to use. The code includes the generation of a standard QR code without a logo and a QR code with a logo, which can be modified and used according to comments.

<&#63;php
include ('phpqrcode.php');
$value = 'http://www.codesc.net';//二维码数据
$errorCorrectionLevel = 'L';//纠错级别：L、M、Q、H
$matrixPointSize = 10;//二维码点的大小：1到10
QRcode::png ( $value, 'ewm.png', $errorCorrectionLevel, $matrixPointSize, 2 );//不带Logo二维码的文件名
echo "二维码已生成" . "<br />";
$logo = 'emwlogo.gif';//需要显示在二维码中的Logo图像
$QR = 'ewm.png';
if ($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, 'ewmlogo.png' );//带Logo二维码的文件名
