Arrays

Arrays, like lists, store multiple values in a single variable. But unlike lists, arrays can contain far more complex data (including lists and even other arrays).

Unlike lists, arrays support multiple dimensions. A single-dimensional array is actually quite similar to a list: It’s a linear collection. A two-dimensional array is more like a grid (imagine a spreadsheet), and data is stored in rows and columns. ColdFusion also supports three-dimensional arrays, which can be envisioned as cubes of data.

If this all sounds somewhat complex, well, it is. Arrays are not as easy to use as lists, but they are far more powerful (and far quicker). Here is a simple block of code that creates an array and displays part of it; the output is shown ...
