Hi,
I sent this email during this summer and nobody replied. I would like to
know your opinion.

Hello,
ext/mbstring is very useful, but from my point of view, some functions
are missing.
I would like to propose the addition of the following functions.
mb_append($str, $piece) and mb_prepend($str, $piece):
To add a $piece to, respectively, the end and the start of $string. It
should consider the text direction, e.g. if $str is Right-to-Left,
mb_append() will add $piece to the end, so the left, of $string.
mb_concat($str, $piece):
If mb_append() and mb_prepend() are too hard to understand by users,
mb_concat() would be pretty much simpler and will act in the same way.
I would insert:
mb_replace($str, $search, $replace):
Complementary to str_replace and less simpler than preg_replace or
preg_filter (and with better performance because it does not need to
compile regex to automata etc.).
mb_pad($length, $piece, $end):
Pretty much like strpad but with multi-bytes considering.
Note that, like mb_append and mb_prepend, we do not speak about left
and right, but start and end.
mb_get_direction($str):
Return LTR or RTL. For one char, it is “easy”. For a string, it is
more complex because we can have embedding directions (a string with
many directions).
mb_get_char($code) or mb_chr($code):
Get Unicode character from a code-point/decimal value representation.
mb_get_code($char) or mb_ord($char):
Get code-point/decimal value representation from of Unicode character.
Finally, it would be great if mb_substr() could consider text
direction (or create a new dedicated function?). For example,
mb_substr($str, 0, 1) will return the first char from the start (and
not the left as it is implemented now).
I think it could help developers to create nice libraries without
requiring a lot of skills in Unicode.
Thoughts?
Best regards :-).
Recently, I crafted a String object that support most of the
propositions written here. Please, see
https://github.com/hoaproject/String (file String.php). The code is very
simple (it implies that it do not need a lot of work to implement it in
PHP I hope). Some interesting methods:
• append;
• prepend;
• pad;
• getIterator (equivalent of str_split);
• \ArrayAccess methods (with support of out-of-bound indexes);
• getByteAt (with support of out-of-bound indexes);
• getCharDirection;
• fromCode;
• toCode.
Hope this helps :-),
Best regards.
