Two quick questions...

Hi all

1) How do I check if a variable's value is numerical or alphabetic? (i.e. integer or string)

2) Is there any in-built command for numbering letters? So: a+3 = d, sort of thing? I know there's way round this but I was just wondering if there was a function so that, for example, hex colour values could be changed easily in calculation using the above equation.

Thanks in advance :o)

1: $str = "17je4";
if (preg_match("/^[a-zA-Z0-9]+$/", $str)) {
echo "The string is alphanumeric";
}
else {
echo "The string is not alphanumeric";
}

2: Not that I know of...

THanks as always, Pyro

I'll make it my mission to find a programming language you don't know.
