Get an image extension from an uploaded file in La

Question

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

The file already exists in a path:

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

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

Using input fields I can get the extension like this:

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

Thanks.

Answer 1

Yet another way to do it:

//Where $file is an instance of Illuminate\Http\UploadFile
$extension = $file->getClientOriginalExtension();

Answer 2

The Laravel way

Try this:

$foo = \File::extension($filename);

Answer 3

You can use the pathinfo() function built into PHP for that:

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

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

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

Answer 4

If you just want the extension, you can use pathinfo:

$ext = pathinfo($file_path, PATHINFO_EXTENSION);

Answer 5

Tested in laravel 5.5

$extension = $request->file('file')->extension();

Answer 6

Or can use the Extension Splitter Trickster::getExtention() function of https://github.com/secrethash/trickster

Trickster::getExtention('some-funny.image.jpg'); It returns jpg
