我创建了一个上传脚本,它也创建了一个工作正常的缩略图,但我现在遇到了一个问题.当我上传一些图像时,exif方向数据会自动旋转我网站上的图像.

我已经尝试在线搜索如何检查数据并将其旋转回去,如果有,但我无法理解我的意图.

到目前为止,这是我的代码：

if(isset($_POST['submit'])) {
        $allowedExts = array("jpg", "jpeg", "gif", "png", "JPG", "GIF");
        $extension = end(explode(".", strtolower($_FILES["file"]["name"])));
        if ((($_FILES["file"]["type"] == "image/gif")
        || ($_FILES["file"]["type"] == "image/jpeg")
        || ($_FILES["file"]["type"] == "image/png")
        || ($_FILES["file"]["type"] == "image/pjpeg"))
        && in_array($extension, $allowedExts)) {
            if ($_FILES["file"]["error"] > 0) {
                echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
            } else {

                $random_numer = rand(10000000, 99999999);
                $newname1 = $random_numer . $_FILES["file"]["name"];
                $scramble = md5($newname1);
                $extension = end(explode(".", $_FILES["file"]["name"]));
                $final_name = $scramble . "." . $extension;

                move_uploaded_file($_FILES["file"]["tmp_name"], "../img/gallery/" . $final_name);
                create_thumbnail($final_name);
                $stmt = $conn->prepare('INSERT INTO gallery (image) VALUES (:image)');
                $stmt->bindParam(':image', $final_name);
                $stmt->execute();

                if ($stmt->rowCount() > 0) {
                    echo "<p class='success'>The Image has been added!
                     <a href='gallery.php'>Please click here to refresh</a></p>";
                } else {
                    echo "<p class='error'>The Image was not added, there was an error.</p>";
                }

            }
        } else {
            echo "Invalid file";
        }
    }

如何使图像不旋转？

解决方法:

你将不得不编写另一个自定义函数,因为没有办法告诉move_uploaded_file忽略EXIF数据,这有点令人失望.
