Remote file size without downloading file

Question

Is there a way to get the size of a remote file http://my_url/my_file.txt without downloading the file?

Answer 1

Php function get_headers() works for me to check the content-length as

$headers = get_headers('http://example.com/image.jpg', 1);
$filesize = $headers['Content-Length'];
