I have a string variable that contains costs in the form 'EUR 123,456,789'

I need to convert it into an integer so that it can be inserted into an INT type mysql field. in other words I need it to be in the form '123456789' without the 'EUR' or the commas separating thousands.

How can I do this in CFML?

thanks

<cfset mystring = "EUR 123,456,789">
<cfset myInt = replace(listlast(mystring, " "), ",", "", "All")>

Unfortunately that doesn't work. It would normally I'm sure, but the problem is that the string variable has been iported into mysql table from an xls spreadsheet and some wierd stuff has happened - I don't know what, but in the string, although it looks like a normal space between the 'EUR' and the first set of digits it obviously isn't.

I would prefer a method that instead of replacing specific characters with "" would just strip away any characters that are not digits. I imagine it will require a regex of some type but I'm rubbish at regex!

I found a solution that works in my case using regex (it's actually really easy!)

<cfset myInt = rereplace(myString,"\D","","all")>

the regex \D corresponds to any character other than a number ---perfect
