for ($char="A";$char<="Z";$char++)
echo "$char - ";

the last char displayed by this script 
is not "Z" but "YZ"
with ever other letter it works as it should

This is an intended behaviour, ++ on strings is "magical" in PHP, like in Perl, so "Z"++ is "AA".

I just hit this aswell. I personally dislike the behaviour. However, rewrite your loop like this to get the expected behaviour:

for ($i=ord('A'); $i<=ord('Z'); $i++)
    echo chr($i)."<br>";
