Pagefield edit via api

[joer80]

I have a template that has a page field that holds several pages, and I have it working that I can add pages to its page field via api, but how do I remove a page without deleting the page it is linking to?  Just unlink it?

This is how I am adding it:

$pagetoadd = $page->id;

//Add page to a page field on 123
$p = wire("pages")->get("id=123");
$p->setOutputFormatting(false);
$p->pageFieldExample = $pagetoadd;
$p->save();

How would I remove one?  Or even remove all and add back what needs to stay?
