| | Creating the database on your database server isn't something we can do for you via a message forum. That's like saying, "Install this app on my phone." I can't exactly do it without physical access to your phone, of course. Do you have a specific question about how to do …  |
 | Domain age plays a big role in SEO directly because it tells Google that the website has been around awhile, and is most likely a legitimate company, and not a fly-by-night temp site or "doorway page". Indirectly, domain age is probably one of the most important, if not the most …  |
| | Sorry, I'm not quite understanding what you are trying to accomplish. On line 22, you are splitting the `$num` variable into an array, so the value of `$num`, after line 22 executes, is now: Array ( [0] => 1 [1] => 1 [2] => 1 [3] => 1 [4] => … |
