Php - Getting file size with an url

I am trying to get a file size of an image from a remote url, I am trying to this like so:

$remoteUrl = $file->guid;
//remote url example: http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png  

$fileSize = filesize($remoteUrl);

But, I get:

filesize(): stat failed for http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png

You can use HTTP headers to find the size of the object. The PHP function get_headers() can get them: 

$headers = get_headers('http://myApp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png', true);
echo $headers['Content-Length'];

This way you can avoid downloading the entire file. You also have access to all other headers, such as $headers['Content-Type'], which can come in handy if you are dealing with images (documentation).

You will need to try a different method, the http:// stream wrapper does not support stat() which is needed for the filesize() function.

This question has some options you might use, using curl to make a HEAD request and inspect the Content-Length header.

That error usually means the supplied URL does not return a valid image. When I try to visit http://myapp/wp-content/uploads/2017/05/Screen-Shot-2017-05-08-at-10.35.54.png it does not show an image in my browser. Double check that the returned URL from $file->guid; is correct.
