The following code creates a new page:

         $p = new Page(); 
         $p->Title = 'Hello'; 
         $p->MenuTitle = $p->Title; 
         $p->URLSegment = $p->Title;
         $p->Content = ''; 
         $p->Status = 'Published'; 
         $p->write(); 
	 $p->doRestoreToStage();
         $p->publish('Stage', 'Live'); 
         $p->flushCache(); 

How can I create a redirector page that redirects to / ?

I don't want a normal page, when someone goes to this URL I want them to be redirected to the home page.

Well instead of creating a new Page(); create a new RedirectorPage();

You also then need to set the fields to point to the page it redirects to. Via

$p->RedirectionType = 'Internal';
$p->ExternalURLID = DataObject::get_one('SiteTree', "URLSegment = 'home'");

Perfect, thanks! Now how can I keep that item from showing up in the menu? I can't figure out how to use ShowInMenus with this.

$p->ShowInMenus = 0; // or false should also work.

How can I validate the urlsegment page already exists before creating the dynamic page?
