in reply to remove first and last character of string

i've thought of using substr but i can't be sure that the number above in quotes will always be the same number of characters

You can use substr() without knowing the number of characters.
To remove the first character of $str: substr($str,  0, 1, '')
To remove the last character of $str : substr($str, -1, 1, '')
Or remove the last character of $str : substr($str, length($str) - 1, '')
Or, just use chop() to remove the last character, as you've already noted.

Cheers,
Rob

    Thanks Rob, but is there a way use this Or remove the last character of $str : substr($str, length($str) - 1, '') to remove the last and first in one line?

        Nice.
        I didn't know that would work. I would have done it as: 
        $s = substr $s, 1, length($s) - 2;

        But I've read the documentation, now ;-)
