IsArray(variable) tells you if a given variable is an array...
Since a 2D array is simply an array of an array, then IsArray(variable[1])
will tell you if the given variable has a second dimension (or at least one
in the first element).
Likewise, IsArray(variable[1][1]) would tell you if it was a 3D array.
Hope this helps

Subject: How many dimensions in a given array?
How do I test to see how many dimensions a given array posseses? This method
gives me all the values of a 2 dimensional array, but I need to know if it's
a 2D array BEFORE I try this ... unless someone knows a craftier way... ???
<cfset a=1>
<cfset aD=1>
<cfloop condition="a LTE ArrayLen(array)">
<cfloop condition="aD LTE ArrayLen(arrayHolder[a])">
<cfoutput>#array[a][aD]#</cfoutput>
<cfset aD=aD+1>
</cfloop>
<cfset a=a+1>
<cfet aD=1>
</cfloop>
Any help appreciated!
