Hi,
mal wieder Zeit für eine neue Array-Funktion. 
Wenn ein Array in einer Spalte mehrfach gleiche Werte enthält (z.B. Datum, IP-Nr), so läßt sich hiermit nach der Anzahl gleicher Werte sortieren.
_Array2DSortByCountSameEntries(ByRef $ARRAY [, $iCol=0 [, $DESCENDING=1]])
Sortiert ein Array nach der Anzahl gleicher Einträge, bei 2D-Array nach Anzahl gleicher Einträge einer angegebenen Spalte.
Wahlweise Sortierung nach fallender (Standard) oder steigender Anzahl gleicher Elemente.
Erfordert die Funktion: _ArraySort_2ary()

; Parameter $ARRAY: Array to sort
; optional $iCol: Column with same entries to sort (default 0)
; optional $DESCENDING: Sort ascending[0]/descending[1] (default 1)
;
; Return Success -1 sorted array
; Failure 0 @error = 1, given array is not array
;
; Requirements _ArraySort_2ary() with #include <array.au3>
