Parameters
Usage To apply the ArrayInsert() function to a multidimensional array, you must specify all but the last index in the array parameter. For example, the following code inserts an element at myarray[2][4]:
    <cfset ArrayInsertAt(myarray[2], 4, "test")>
Throws If this function attempts to insert an element at position 0, or specifies a value for position that is greater than the size of array, this function throws an InvalidArrayIndexException error.
Example
    <h3>ArrayInsertAt Example</h3><p>
    <!--- create a new array --->
    <cfset DaysArray = ArrayNew(1)>
    <!--- populate an element or two --->
    <cfset DaysArray[1] = "Monday">
    <cfset DaysArray[2] = "Tuesday">
    <cfset DaysArray[3] = "Thursday">
    <!--- add an element before position 3 --->
    <p>Add an element before position 3:
       <cfoutput>#ArrayInsertAt(DaysArray,3,"Wednesday")#</cfoutput>
    <p>Now output the array as a list:
    <cfoutput>#ArrayToList(DaysArray)#</cfoutput>
    <!--- The array now has four elements. Element 3, "Thursday", has become
    element four --->
