PHP使用imagecopyresampled保留exif数据

Question

I'm wondering if is a way to keep exif data of original image in image created by imagecopyresampled function. My code:

$randomName = Functions::generate_random_string(10);
$img = imagecreatefromjpeg($_FILES["file"]["tmp_name"]);
$imageSize = getimagesize($_FILES["file"]["tmp_name"]);
$ratio = 1 / ($imageSize[0] / $imageSize[1]);
$newWidth = 2560;
$newHeight = round($newWidth * $ratio);
$tmp_img = imagecreatetruecolor( $newWidth, $newHeight );
imagecopyresampled( $tmp_img, $img, 0, 0, 0, 0, $newWidth, $newHeight, $imageSize[0], $imageSize[1] );

Works fine but in created image there is no exif data.

Answer 1

You can capture the exif data and save it to the database as meta data for the file.
