PHP generates QR code with icon code example

PHP generates QR code with icon code example (PHP QR Code QR code generation class library)

public static function png($text, $outfile=false, $level=QR_ECLEVEL_L, $size=3, $margin=4,  
$saveandprint=false)  
{ 
    $enc = QRencode::factory($level, $size, $margin); 
    return $enc->encodePNG($text, $outfile, $saveandprint=false); 
}

Simple example:

include 'phpqrcode.php'; 
QRcode::png('https://www.cuplayer.com');

QR code with LOGO watermark:

<?php
include 'phpqrcode.php';  
$value = 'https://www.cuplayer.com'; //二维码内容 
$qr_eclevel = 'H';//容错级别 
$picsize = 6;//生成图片大小
QRcode::png($value, 'qrcode.png', $qr_eclevel, $picsize);//生成二维码图片
$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, 'myxzy.png'); 
echo '<img src="myxzy.png">'; 
?>
