Once the file is uploaded to your server, you can do whatever you want with it. PHP will provide you with the temporary location of the uploaded file in the variable $_FILES['your_form_element_name']['tmp_name']

一旦文件被上传到你的服务器，你就可以做任何你想做的事情。PHP将为您提供变量$_FILES中上传文件的临时位置['your_form_element_name']['tmp_name']

From there you can use Imagick to resize the file, and then upload the resized image to S3 alongside your original image.

从那里你可以使用Imagick调整文件大小，然后将调整后的图像上传到S3。

Imagick has a Imagick::thumbnailImage() method which is really easy to use.

Imagick有一个Imagick::thumbnailImage()方法，它很容易使用。
