Re: can i rely on ctype?

Hi,

Deprecating ctype makes a lot of sense. I have a lot of code
using PCRE with "/^d*$/" to avoid the casting
errors. It's also of limited utility in a multi-lingual
setting - even though it is Locale aware.

Having a unicode friendly char_is_* makes a huge amount of
sense. Anyway, ctype doesn't like my name ;) on most English
sites if its used.

A pretty major change that makes perfect sense. When PHP6 is
there,
there are char_is_*-functions using ICU (the unicode
library). Those
functions do everything that ctype does in a more coherent
way,
example:

swalkitchy:~/programming/php/php6> ./php-unicode -r
'var_dump(ctype_digit(123));'
bool(false)
swalkitchy:~/programming/php/php6> ./php-unicode -r
'var_dump(char_is_digit(123));'
bool(true)

So you don't have to explicitely cast to string anymore when
you want
to check that a value you got is either an integer or a
string
containing only an integer, which is more like string/int
juggling
works in the rest of php ... to summarize, you have new
functions
offering the same functionality and more, and have a cleaner
API ...
so the rational thing to do is deprecate the old
functionality. It
won't be gone, but folks should be made aware that better
things are
available.

Regards,
Stefan
