"Array String-Konvertierung" auftreten

ich codeigniter verwende, ich bin immer Post Wert im zweiten Array (Listingdata) mit Methode $ this-> input-> post(); , aber mein erstes Array bekommt einen dynamischen Schlüssel und Wert, dann geben diese beiden Array-Diffs mir eine Ausgabe, aber einige Zeit bekommen einen Fehler.

Answer 1

Dies liegt daran, array_diff Werte vergleicht, nachdem die beiden verglichenen Werte in String typecasting (siehe documentation notes).

Beide Arrays enthalten ein weiteres Array (ebay_user und zweite pictureUrl).

Siehe this answer für rekursive Array_diff, die in Ihrem Fall funktionieren sollte.
