A foreach loop is a specialized conditional loop that states to loop for
each item in a collection.
A conditional loop over a list looks something like this:
<cfset idx = 1>
<cfset length = listLen(somelist)>
<cfloop condition="idx LTE length">
<!--- do something --->
<cfset idx = idx + 1>
</cfloop>
An iterative loop over a list looks like this:
<cfset length = listLen(somelist)>
<cfloop index="idx" from="1" to="#length#">
<!--- do something --->
</cfloop>
A foreach-like loop looks like this:
<cfloop index="idx" list="#somelist#">
<!--- do something --->
</cfloop
There is another CFLOOP that functions much like the last example for
handling the elements in a structure of the items in a COM collection.
Other languages actually use a statement called "foreach" to handle most
kinds of collections (whether they be datatypes like lists or arrays or
structures or higher order collections).

What is a "foreach" loop? Do you mean a conditional loop (i.e. for each
iteration test a condition and if met break out of the loop)? If so...yes
