ArrayIsEmpty(array)

True, if the array is empty; False, otherwise.

You can test whether an element of a higher level dimension of a multidimensional array is empty by specifying the element in the ArrayIsEmpty function. To test whether the first row of the two-dimensional array MyArray is empty, use the following function:
ArrayIsEmpty(MyArray2[1])

<h3>ArrayIsEmpty Example</h3> 
<!--- Create a new array. ---> 
<cfset MyArray = ArrayNew(1)> 
<!--- Populate an element or two. ---> 
<cfset MyArray[1] = "Test"> 
<cfset MyArray[2] = "Other Test"> 
<!--- Output the contents of the array. ---> 
Your array contents are: 
<cfoutput>#ArrayToList(MyArray)#</cfoutput> 
<!--- Check to see if the array is empty. ---> 
Is the array empty?: 
<cfoutput>#ArrayIsEmpty(MyArray)#</cfoutput> 
Now, clear the array: 
<!--- Now clear the array. ---> 
<cfset Temp = ArrayClear(MyArray)> 
<!--- Check to see if the array is empty. ---> 
Is the array empty?: 
<cfoutput>#ArrayIsEmpty(MyArray)#</cfoutput>
