PHP---将两张身份证照片合并为一张
最近要开发一个功能,前端上传身份证照片的正反面,后台需要将该这两张身份证照片进行合并。

具体代码示例:
public function mergeImage($one = '',$two = '',$name = 'idcard') { $rootPath = input('server.REQUEST_SCHEME') . '://' . input('server.SERVER_NAME'); $oneImgPath = $rootPath . $one; $twoImgPath = $rootPath . $two; $oneImgObj = getimagesize($oneImgPath); $twoImgObj = getimagesize($twoImgPath); $oneImgWidth = $oneImgObj[0]; $oneImgHeight = $oneImgObj[1]; $twoImgWidth = $twoImgObj[0]; $twoImgHeight = $twoImgObj[1]; $canvasWidth = $oneImgWidth > $twoImgWidth ? $oneImgWidth : $twoImgWidth; $canvasHeight = $oneImgHeight + $twoImgHeight; $imgOne = imagecreatefromjpeg($oneImgPath); $imgTwo = imagecreatefromjpeg($twoImgPath); $canvas = imagecreatetruecolor($canvasWidth,$canvasHeight); imagefill($canvas,0,0,imagecolorallocate($canvas,255,255,255)); $imgOneX = ($canvasWidth - $oneImgWidth) / 2; $imgTwoX = ($canvasWidth - $twoImgWidth) / 2; imagecopyresampled($canvas,$imgOne,intval($imgOneX),0,0,0,$oneImgWidth,$oneImgHeight, $oneImgWidth,$oneImgHeight); imagecopyresampled($canvas,$imgTwo,intval($imgTwoX),$oneImgHeight,0,0,$twoImgWidth,$twoImgHeight, $twoImgWidth,$twoImgHeight); $desPath = 'storage/upload/idcard/'.$name.'.jpg'; // 文件名字 file_exists($desPath)&&unlink($desPath); imagejpeg($canvas,$desPath,100); return $desPath; }
具体使用,仅需要掉用该方法的时候,传入需要合并的照片即可。
// 正面 反面 命名 $result = $this->mergeImage($idcardFront,$idcardBack,'idcard-45124545');
打完收工!
