Yep, providing youre using session_start() and session_register(_SESSION)
you can assign any type of data, just like a regular hash.

Nope - you'll have to 'roll your own' by looping though the set, or (if you

Can't you just count the elements and then divide the total by the count?
It seems pretty obfuscating to consider a function that takes an unknown
number of elements, unless it were an array... still, seems pretty easy to
count and divide total... doesn't it?

If you're doing it on values from a database
What database are you using?
MySQL has a SUM function which automatically selects the total of a column.

I'm not sure if this will help but using mb_send_mail() instead of mail()
solved the problems I had with Japanese characters...
However, it might be the mail client itself. Check if they had no problem

doing this will show you the sum of all the scores:

eg, if the scores were 5, 2, 5, 8, and 2 then this sql should return 22

Hi,
you would be better off with preg_match, as its a little quicker apparently.
try:
preg_match(/^[:0-9a-f]*$/i,$string)
or change the * to a + to ensure $string is not null
the main problems you had:
- not ensuring that only those characters are found by using ^ and $
- not allowing
try this
ereg(^[a-zA-Z0-9:]*$,$string)
all your's is doing is looking for any char in $string that's a-z or A-Z or
0-9 or :
instead of all chars, from start to end, being them
