Several ways that I can think of:

      * use the file_get_contents() which like you said, could be
      * shell out to wget to retrieve just the headers for the path.
        You'd be looking for a 200 return code, which indicates the URI
      * lastly, you could use fopen() to open the file, and use the
        return from the fopen() call to indicate a success of failure
