wget combined with php

Question

Is there some way to type a URL in a text field, click submit on my page and use PHP to download all content from that URL with wget, saving the files to a folder on my server?

Answer 1

Yes.

You can use PHP exec() function (or similar) to execute external commands (such as wget).

If you need all site assets then I'd use the options for wget. Otherwise, if you just need the page content, I'd do it natively with PHP as suggested in the comment from DaveRandom.

Note: Use at your own risk... The scenario you describe is dripping with evil.
