這裡PHP使用phpqrcode生成帶LOGO影象的二維碼，使用起來很方便，程式碼中含生成不帶Logo的標準二維碼和生成帶Logo的二維碼，可根據需要進行改進：

<?php
include ('phpqrcode/phpqrcode.php');
createQR('http://www.discuz.ailab.cn/','ewm','');
echo "二維碼已生成<img src=\"ewm.png\">" . "<br />";

function createQR($text,$imgName,$logo='',$errorCorrectionLevel = 'L',$matrixPointSize = 10){
	QRcode::png ($text,$imgName.'.png',$errorCorrectionLevel,$matrixPointSize,2);
	if($logo){
		$QR = imagecreatefromstring(file_get_contents($imgName.'.png'));
		$logo = imagecreatefromstring(file_get_contents($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,$imgName.'.png' );//帶Logo二維碼
	}
}
?>
