Laravel文件扩展名为数组值

Question

I am trying to get the file extension of the files from the multiple file input array.

I tried to use File::extension() but it expects a string and I have an array.

I don't need this value for the validation so I can't use Laravel validation. Thanks

I am trying to get the file extension of the files from the multiple file input array.

Then loop over the $_FILES array.

foreach ($_FILES as $key => $file) {
    $extensions[$key] = \File::extension($file['name']);
}

The above presumes no fancy/opinionated $_FILES structure mutations ;p
