I'm planning to use PHP for a simple requirement. I need to download a XML content from a URL, for which I need to send HTTP GET request to that URL.
How do I do it in PHP?
Unless you need more than just the contents of the file, you could use file_get_contents.
$xml = file_get_contents("http://www.example.com/file.xml");
For anything more complex, I'd use cURL.
