for( $i = "a"; $i <= "z"; $i++ ) {
}
Not entirely too sure why, but the above works. And
it's really cool that it does. :)
However, it doesn't work as one would expect (aside
from the fact that it works at all :p). Just looking at
it, I would think that it would iterate from "a" to "z"
and stop. But in fact, what it's doing is going from
"a" to "yz", having iterated all of the alphabet using
double letters ( "aa", "az", "bb", "bz" ... "yy", "yz").
Why is that?
Just trying to understand. :)
Thanks for any help/insight you can provide!
