You may already be familiar with file_get_contents() for reading the contents
of a local file but did you know that you can use it to read the contents of a
remote file or site? You can then use file_put_contents() to write the file’s
contents back to disk:
file_put_contents('./some/local/file', file_get_contents('http://phpave.com'
Both functions are binary safe so you should be fine to work with files that
are not simply full of ASCII text.
