Hi all,
What do you think is the best way to display string 'abcdef' as 'fedcba'?
Any ideas appreciated.
Thanks in advance.

What I meant was that I tested the script and it worked, so I didn't
spot the flaw (wich is obvious and you were right).
No big deal.

I don't know. What is the leading preference nowadays? Does it matter?
Somewhere in the past I learned it with the square brackets like an
array and it still works like that. Maybe it isn't 'right' (Stut?), but
that is the way I picked it up.

No, they will be deprecated as of PHP6. (Square brackets used to be, but
have been undeprecated and are back in favour!)
$tmp = '';
$str = 'abcdef';
for ($i = strlen($str)-1; $i = 0; $i--) {
$tmp.= $str{$i};
