De vraag is, ik heb een lijst met leden, moet ik dan in de body een loop aanmaken, die op 1 pagina 50 keer het volgende uitprint?
echo json_encode($compacted, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);
Dan is het antwoord nee. En JSON string is niet te combineren met HTML-output.
https://search.google.com/structured-data/testing-tool
Ik lees op verschillende plekken dat hij in de head en body mag staan
Laat je URL met je JSON-string eens zien?

Wat laat je browser zelf zien?
alle php variabelen zijn gevuld.
ik krijg alleen 1 foutmelding in die code:
Het kenmerk publisher.itemtype heeft een ongeldige waarde.
Edit:
Het is dus JSON LD (Linked Data), dat maakt het dus weer anders dan het gewone JSON.

Inmiddels zie ik ook dat het JSON+LD is i.p.v. het gewone JSON. Dat verandert de zaak, en dat kan wel in je HTML-document.
