我被要求创建一个将要求输入文本和上传照片的内容。然后创建一个图像，其中显示这些。然后必须将生成的图像保存到服务器（不使用数据库）。我在这里有一个成功生成图像的代码（在这种情况下我使用了 imagejpeg 和 imagecreatefromjpeg。但是我仍然需要将它保存到具有文件扩展名 .jpg 的服务器。我还需要给它一个唯一的名称。
我尝试使用header('Content-Disposition: attachment; filename="image.jpg"'); 但它所做的是将其保存到 PC 而不是服务器中。下面是我的代码。请随时编辑它。另外，请留下一些评论，以便我理解它，而不仅仅是复制粘贴。非常感谢您的帮助。我现在真的需要让它工作。再次感谢
