Creating arrays

In ColdFusion, you declare an array by assigning a variable name to the new array and specifying its dimensions, as follows:

<cfset mynewarray=ArrayNew(x)>

where x is the number of dimensions (from 1 to 3) in the array that you want to create.

Once you declare an array, you can add array elements, which you can then reference using the elements' indexes.

For example, suppose you declare a 1D array called "firstname":

<cfset firstname=ArrayNew(1)>

The array firstname holds no data and is of an unspecified length. Next you add data to the array:

<cfset firstname[1]="Coleman">
<cfset firstname[2]="Charlie">
<cfset firstname[3]="Dexter">

After you add these names to the array, it has a length of 3.
