function anchor_fix($anchor){  // the match comes as an array  // the whole match (what we want) is the 0th element  if (! preg_match('/\sid="/i', $anchor[0])) {	 return preg_replace('/name="([^"]*)"/i', 'id="$1" $0', $anchor[0]);  } else {	 // already has an id!	 return $anchor[0];  }}/* usage */echo preg_replace_callback('/
    
     ]*>/i', 'anchor_fix', file_get_contents('page.html'));
