Description:
Reverses the order of elements in a one-dimensional array. This function takes a one-dimensional array and returns a new one with the values from the first in reverse order.

Return Values:
Returna a new one dimensional array.

Example:

<CFSET Numbers = "1,2,3,4,5">
<CFSET NumbersArray = ListToArray(Numbers)>
<CFSET NumbersArray = ArrayReverse(NumbersArray)>

<CFLOOP INDEX="I" FROM="1" TO="#ArrayLen(NumbersArray)#">
<CFOUTPUT>
#NumbersArray[I]#<BR>
</CFOUTPUT>
</CFLOOP>

Parameters:
