How do I access file mimeType in Laravel 5.8?

Question

I had this

$file = array('file' => Input::file('file'));

and

dd($file); return

How do I access file mimeType via the Laravel way ?

try `$file->getClientMimeType()` or `$file->getMimeType()` [ref](https://stackoverflow.com/questions/39594854/why-does-laravels-getmimetype-method-identify-a-file-as-application-octet-st) — iamab.in, Mar 09 '20 at 18:34

You can the mime type of the file retrieve it like this:

$file['file']->getMimeType();

I tried `dd($file[0]->getMimeType());` I got `Undefined offset: 0` – code-8 Mar 09 '20 at 18:37
`dd($file['file']->getMimeType());` – Rimble Mar 09 '20 at 18:38
@cyber8200 Oops it should be `'file'` like @Rimble said. – Chin Leung Mar 09 '20 at 18:40

You may use one of this functions:

$file['file']->getClientMimeType();

The client mime type is extracted from the request from which the file was uploaded, so it should not be considered as a safe value. For a trusted mime type, use getMimeType() instead (which guesses the mime type based on the file content).
$file['file']->getMimeType();

The mime type is guessed using a MimeTypeGuesserInterface instance, which uses finfo_file() then the "file" system binary, depending on which of those are available.
