[cfaussie] RE: Count occurances of a character in a string

[Brett Payne-Rhodes]

Thanks everyone. Lots of great ideas and links.
In the end I looked at some UDF examples of similar functions and then 
wrote my own very simple UDF:

<cfscript>
function countChar(srchString, srchVal) {
        var charCount=0;
        var strLen=len(srchString);
        for (idx=1; idx LTE strLen; idx=idx+1) {
                if (mid(srchString, idx, 1) eq srchVal) {
                        charCount = charCount + 1;
                }
        }
        return charCount;       
}
</cfscript>
Thanks again,
Brett

This would work great if CF treated contiguous delimiters (ie empty items)
as list elements.
Your example will fail for things like
ListLen("hello dolly", "l").
Was an explanation ever provided by Allaire as to why empty items are
ignored?

How about this:
listLen(originalString,characterToCount)-1
No special non standard functions to get. Just bog standard cf
tags/functions.
