If you see the above example code carefully, you'll find the download link pints to a 'download.php' file, the URL also contains image file name as a query string. Also, we've used PHP urlencode function to encode the image file names so that it can be safely passed as URL parameter, because file names may contain URL unsafe characters. A URL can be used as a filename with this function if the fopen wrappers have been enabled. See fopen for more details on how to specify the filename. See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide.

This example shows how to download a file from the web on to your local machine. By using io.Copy() and passing the response body directly in we stream the data to the file and avoid having to load it all into the memory - it’s not a problem with small files, but it makes a difference when downloading large files.

We also have an example of downloading large files with progress reports.

Download Php File From Url Link

If you want to use the filename from the url, you can replace the filepath variable in DownloadFile with path.Base(resp.Request.URL.String()) and import the path package.
