Re: ord() on binary strings

My argument was that ord() semantics and docs say that it works on _characters_ and this simply does not make sense for the binary strings. If we really want ord() to work on binary type, fine, but we'd better have docs that make sense then. -Andrei On Sep 9, 2005, at 12:09 AM, Derick Rethans wrote:

Did Andrei have a reason besides the docs? Even without IS_UNICODE/IS_BINARY it sounds like the docs could use tuning anyway, no?

Andrei: The docs say "Return ASCII value of character", which doesn't

        make sense for binary. You can use bin2hex(), bin2hex() == ord()
        for binary.

(Which is not true, as it doesn't return the ordinal value, just a two digit hex string) Derick: anyway, ord() always worked on string like this, seems

        strange to break it (and yes, it already did)

Andrei: you had binary strings before? Derick: normal strings of course, but it came from a file, so it turned

        binary and ord() started failing

Andrei: Then you should fix your code and convert that binary to

        something sensible if you are reading text

Derick: it's not text, it's binary Andrei: if it's binary, why do you need to know the ascii value Derick: Because I'm converting a binary file to a C file (for the

        timezone database)

Then he continues saying that it's Ok to break BC in unicode mode. regards, Derick --Derick Rethans http://derickrethans.nl | http://ez.no | http://xdebug.org --PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
