現(xiàn)在二維碼是我們一些軟件站或下載站常用的一種東西了,特別是微信都會(huì)使用二維碼來(lái)加好友,下面我來(lái)介紹利用php生成二維碼多種方法.

方法一,這種生成就是一個(gè)二維碼中間不帶圖片的,直接調(diào)用google的一個(gè)功能就實(shí)現(xiàn)了,代碼如下:

$urlToEncode="http://gz.altmi.com";

generateQRfromGoogle($urlToEncode);

function generateQRfromGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0') //開(kāi)源代碼Vevb.com

{

    $url = urlencode($url);

    echo '<img src="http://chart.apis.google.com/chart?chs='.$widhtHeight.'x'.$widhtHeight.'&cht=qr&chld='.$EC_level.'|'.$margin.'&chl='.$chl.'" alt="QR code" widhtHeight="'.$size.'" widhtHeight="'.$size.'"/>';

}

生成像微信一樣中間有l(wèi)ogo二維碼,代碼如下:

// QR Code + Logo Generator QR圖片中間加logo

$data = isset($_GET['data']) ? $_GET['data'] : 'http://www.survivalescaperooms.com';

$size = isset($_GET['size']) ? $_GET['size'] : '130x130';

$logo = isset($_GET['logo']) ? $_GET['logo'] : './20130128160755.jpg';//中間那logo圖

$chl = urlencode($logo);

$png = "http://chart.googleapis.com/chart?chs=$size&cht=qr&chl=$chl&chld=L|1&choe=UTF-8";

$QR = imagecreatefrompng($png);//外面那QR圖

if ($logo !== FALSE) {

  $logo = imagecreatefromstring(file_get_contents($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);

}

header('Content-type: image/png');

imagepng($QR);

imagedestroy($QR);
