Hinweise zur Funktion array_diff

array_diff – Berechnen Sie die Differenz von Arrays

Beschreibung:

array array_diff ( array $array1 , array $array2 [, array $... ] ) Der Vergleich wird in array1 aber zurückgegeben Werte, die nicht in array2 oder einem anderen Parameterarray enthalten sind. Beachten Sie, dass die Schlüsselnamen unverändert bleiben.

Hinweis: Diese Funktion überprüft nur eine Dimension des mehrdimensionalen Arrays. Wenn Sie tiefere Dimensionen vergleichen möchten, müssen Sie eine andere Funktion schreiben. In der heutigen Arbeit ist ein solcher Bedarf aufgetreten, daher habe ich eine Funktion zum Vergleich tieferer Dimensionen geschrieben.
