Hi All.
I've got a question regarding the length of binary strings in MB String.
Now strlen(file_get_contents('file.bin')) returns string length in bytes. However, if in php.ini we overload the mb_strlen function in place of strlen, specifying mbstring.internal_encoding='UTF8', the result will be wrong.
In this regard the question is whether or not a function like mb_strleninbytes expected to return the string lenght in bytes is going to be introduced? Or, do you plan to use mb_strlen($str, ASCII) everywhere instead?
You can use mb_orig_strlen() where the byte-wise behaviour is
needed, when strlen() is overloaded by mb_strlen(). The same applies to
other mbstring counterparts (e.g. substr() - mb_substr() - mb_orig_substr()).
This is an undocumented feature though.
BTW, while it's found useful sometimes, it's also discouraged to use function
overloading as strlen() is the only reasonable way to retrieve the length
of a binary object in bytes at this time. I couldn't assure this, but
sizeof() / count() will likely replace that functionality of strlen() and
strlen() will probably be used solely to get the actual character count.
