Hi,
I've written a short regexp which will *count* how many capital letters
are in a given string (the woefully simple: '/[A-Z]/')
Although it's an English language web site, I'm curious how you'd
count capital letters that span beyond just the standard A-Z.
For example characters such as the Latin capital letter S with Acute.
I'm not interested in covering all possible character sets, but I
don't want to piss-off any Europeans who may register on the site and
want to use one of "their own" capital letters.
Anyone approached this before?
Cheers,
Rich
Rich:
Can't say that I have, but try this off the top of my head:
1. Explode the string into two arrays (array1, array2);
2. Lowercase one array;
3. Use array_dif.
4 Count array_dif.
Cheers,
tedd
