如何获取对象数组字段？

I currently receive an array with this structure:

Array
(
    [0] => Symfony\Component\HttpFoundation\File\UploadedFile Object
        (
            [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
            [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => apple-tv-ad
.jpg
            [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => image/jpeg
            [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 36555
            [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
            [pathName:SplFileInfo:private] => /private/var/tmp/phpe6INuk
            [fileName:SplFileInfo:private] => phpe6INuk
        )

)

When I try to print_r($file[0]['originalName']); I receive a 500 internal server error. I try to upload a file via an AJAX call. Once my mediaUpload method is called, I want to make the database entry with the appropriate values received through this array. I am just stuck at how to access it. Any help would be appreciated.

Thanks!

Use the getClientOriginalName() method. (Sorry for the short answer, but that's pretty much all there is to it.)

$name = $file[0]->getClientOriginalName();

The UploadedFile object has different accessor methods you can use to get all the different pieces of information you need. They're all there in the API docs I linked.
