How can you check if two arrays are the same using CFML?

Question

Using CFML (ColdFusion Markup Langauge, aka ColdFusion), how can you compare if two one-dimensional arrays are the same?

Answer 1

Assuming all values ​​in the array are simple values, it is easiest to convert arrays to lists and just compare strings.

<cfif arrayToList(arrayA) IS arrayToList(arrayB)>
    Arrays are equal!
</cfif>

Not as elegant as the other solutions proposed, but they are simple.

CFML, java. Adobe (http://coldfused.blogspot.com/), ColdFusion java- (java.util.List). , Java CFML.

, 2 , , , equals. , , .

<cfset array1 = listToArray("tom,dick,harry,phred")/>
<cfset array2 = listToArray("dick,harry,phred") />
<cfset array3 = listToArray("tom,dick,harry,phred")/>

<cfoutput>
Array2 equals Array1 #array2.equals(array1)# (returns a NO) <br/>
Array3 equals Array1 #array3.equals(array1)# (returns a YES) <br/>
</cfoutput>
