Where are Pages module data stored?

They are store in exp_sites in the site_pages column, in a base64 encoded serialized array:

$this->EE->db->select('site_pages')
             ->where('site_id', $this->EE->config->item('site_id');

$query = $this->EE->db->get('sites');

$site_pages = unserialize(base64_decode($query->row('site_pages')));

print_r($site_pages);

Array
(
    [uris] => Array
        (
            [207] => /my/pages/uri/
        )

    [templates] => Array
        (
            [207] => 2
        )

)

[edit] looks like Rob beat me to this 😊

Thanks, Rob and Erik.

What I’m attempting to do is this: Given that I have the ‘page_uri’ (only), I need to grab the contents of a particular field displayed on this page and then output it in a template.

Either of you know how I might get the ‘entry_id’ of a page whose ‘page_uri’ I have? With that, I could find the field’s contents.

TIA
