Never realized that you could address a string as an array of chars, which you are doing.  Could that be the issue?  Or did I learn something new?  Or should you have used substr to remove that last char?

Jim:

I guess you learned something new -- that's good.

A string is just a "string" of chars.

As such, if you define:

$a = "tedd";

then:

$a[0] is 't';
$a[1] is 'e'
$a[2] is 'd'
$a[3] is 'd'

The only confusing thing here is the length of the string -- in this case the length of this string is four, but $a[4] has not been defined.

Cheers,

From what I do know, there shouldn't be an a[4].
In any case, let's assume that there is a bug in the string logic that you're using. Why not just use substr?

$topic = substr($topic,0,-1);
