$page->getArray() and field type Page references

[Mackski]

I have many pages with multiple Page fieldtypes.
What I'm looking at doing is caching the related pages, however I cannot obtain ID references via $page->getArray(). I only get [title] returned. Is there a way to return Page typefield field ID references to other pages without hitting the DB?

In ProcessWire 3.x (I think only 3?) you can use implode like so:

$pageIDsString = $yourPageArray->implode('|', 'id');
//echo $pageIDsString;// returns 1234|2345|8976 etc..

You can choose your delimiter and the property to implode by. There's other interesting methods here.

You can use

$page->getIterator();

instead of

$page->getArray();
