When is "z" != "z" ?

[tedd <tedd@xxxxxxxxxxxx>]

Hi gang:

Here's your opportunity to pound me again for not knowing the basics of php.

I vaguely remember something like this being discussed a while back, but can't find the reference.

In any event, if one uses --

for ($i="a"; $i<"z"; $i++)
  {
  echo($i);
   }

-- it stops at "y"

But, if you use --

for ($i="a"; $i<="z"; $i++)
  {
  echo($i);
   }

-- it prints considerably more characters after "z" than what one would normally expect -- why is that?

Just stopping at "z" would seem to make more sense, wouldn't it? After all, when $i = "z" in the first expression, then wouldn't $i be equal to "z" in the second expression and thus halt the operation?

What am I missing here?

Thanks.

tedd
