Scraping Js file with Simple HTML DOM

Question

Im using Simple HTML DOM to scrape a Javascript file like this:

$html = file_get_html('http://www.The-Javascript-File.js');
echo $html;

The problem is that I get this error in console:

Resource interpreted as Script but transferred with MIME type text/html: http://www.The-Javascript-File.js

Obviously because its a HTML parser('file_get_html')...Is there something I can do with Simple HTML DOM to get the file as a proper js file?

If the remote URL is a script (and not an HTML page) do you really need to be using Simply HTML DOM? Why not just do $contents = file_get_contents('The-Javascript-File.js')? — jszobody

Wait .. what .. why are you trying to read a JavaScript as HTML? If you just want the file user file_get_contets? — Halcyon

Wait, why you are using that instead of just a file_get_content? — chris-l

SimpleHTMLDom, as the name indicates is for parsing HTML, not JavaScript. If you want to parse JavaScript, then why not simply use file_get_contents()?

$js = file_get_contents('http://www.example.com/file.js');
//parse it!

There's also UglifyJS (originally based on parse-js). You may want to check that out, as well.
