You posted this in the PHP forum as a PHP script :D

Just if PHP coders wanted to do this...

Ya, just finally got around to doing it in JS. Seemed useful enough...

yeah, I would have said so. It's a very nice function. Plus, not all people have PHP.

:thumbsup:

What about decimal points, or negative numbers? :)

if ( num.charAt(0) == "-" ) {
//negative
}

too lazy to do it now, maybe later.

Could be a method for strings and numbers! Only changes are
Number.prototype.toEnglish = function()
{
return this.toString().toEnglish();
}

String.prototype.toEnglish = function() {
num = this.replace(/[^0-9]/, ""); //removes all non-numeric characters.And, of course, the usagedocument.write(("1275h33").toEnglish());
