i'm using file_get_contents to retrieve the content of external webpages and then i log the received content into a txt file.
The problem is i've founded some void in the middle of the page, and since that part of page is a human written text i exclude void is really present in the page.
So i've an output like this:
Lorem ipsum void sit avoidet, consectetur adipisici elit, sed eiusmod tempor
So which characters may be returned as "void" with file_get_contents?
Thanks a lot
