php調用google介面產生二維碼執行個體

例子，調用google介面來實現二維碼。 ?php $data = isset($_GET['t']) ? $_GET['t'] : 'http://www.XXX.com'; $size = isset($_GET['size']) ? $_GET['size'] : '150x150'; $logo = isset($_GET['logo']) ? $_GET['logo'] :"./image/logo.jpg"; $chl = urlencode($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 //以下是二維碼產生的主要代碼 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); //銷毀二維碼映像 imagedestroy($QR); ?> 複製代碼
