从Laravel中的上传文件获取图像扩展名 [英] Get an image extension from an uploaded file in Laravel

问题描述

我一直试图从上载的文件中获取扩展名，在google上搜索，没有结果.

I have been trying to get the extension from an uploaded file, searching on google, I got no results.

该文件已存在于路径中:

The file already exists in a path:

\Storage::get('/uploads/categories/featured_image.jpg);

现在，如何在上方获取此文件的扩展名?

Now, How can I get the extension of this file above?

使用输入字段，我可以得到如下扩展名:

Using input fields I can get the extension like this:

Input::file('thumb')->getClientOriginalExtension();

谢谢.

推荐答案

您可以使用为此，PHP内置了pathinfo()函数:

$info = pathinfo(storage_path().'/uploads/categories/featured_image.jpg');
$ext = $info['extension'];

或更简洁地说，您可以通过一个选项直接获取它；

Or more concisely, you can pass an option get get it directly;

$ext = pathinfo(storage_path().'/uploads/categories/featured_image.jpg', PATHINFO_EXTENSION);
