I'm trying to loop to get the elements from domains, impressions (and sub elements). I managed to get the first parts: pageid, step_order, page_url. I'm having trouble with in_links and out_links and their child arrays. Anyone have ideas on how to pull that data?

Answer 1

Here's how you get the domains from in_links. The others are similar (but I'm not sure what the indexes in the impressions sub-array represent).
foreach ($array as $element) {
foreach ($element['in_links']['domains'] as $domain => $count) {
echo "Domain: $domain, Count: $count\n";
}
}
