(PHP 4 >= 4.0.6, PHP 5)
mb_strcut — Obtener parte de un string
Descripción
string mb_strcut
( string
$str
, int $start
[, int $length
[, string $encoding
]] )mb_strcut() extrae un substring de un string de forma similar a mb_substr(), pero opera sobre bytes en lugar de caracteres. Si la posición de corte ocurre entre dos bytes de un carácter multibyte, dicho corte se realiza empezando desde el primer byte del carácter. Esta es también la diferencia con la función substr(), la cual simplemente cortaría el string entre los bytes, resultando así una secuencia de bytes malformada.
Parámetros
-
str -
El string a cortar.
-
start -
Posición de inicio en bytes.
-
length -
Longitud en bytes.
-
encoding -
El parámetro
encodinges la codificación de caracteres. Si es omitido, será usado el valor de la codificación de caracteres interna.
Valores devueltos
mb_strcut() devuelve la porción de
str especificada por los parámetros
start y
length.

What the manual and the first commenter are trying to say is that mb_strcut uses byte offsets, as opposed to mb_substr which uses character offsets.
Both mb_strcut and mb_substr appear to treat negative and out-of-range offsets and lengths in the basically the same way as substr. An exception is that if start is too large, an empty string will be returned rather than FALSE. Testing indicates that mb_strcut first works out start and end byte offsets, then moves each offset left to the nearest character boundary.

diffrence between mb_substr and mb_substr
example:
mb_strcut('I_ROHA', 1, 2) returns 'I_'. Treated as byte stream.
mb_substr('I_ROHA', 1, 2) returns 'ROHA' Treated as character stream.
# 'I_' 'RO' 'HA' means multi-byte character

I found this function to be extremely useful.
Here is a practical example, showing the difference between substr(), mb_substr() and mb_strcut():
<?php
mb_internal_encoding('UTF-8');
$string = 'cioèòà';
var_dump(
substr($string, 0, 6),
mb_substr($string, 0, 6),
mb_strcut($string, 0, 6)
);
?>
Output:
string(6) "cioè?"
string(9) "cioèòà"
string(5) "cioè"
Explanation:
$string is long 9 bytes
c - 1 byte
i - 1 byte
o - 1 byte
è - 2 bytes
ò - 2 bytes
à - 2 bytes
substr() works with bytes, so it returns a string which is exactly 6 bytes long. Thus, it truncates the ò character.
mb_substr(), instead, works with characters, so it returns a string which is exactly 6 characters long (but in this case is 9 bytes long).
mb_strcut() works exactly as substr(), but, if the last byte appears to be truncated, it simply omits the character.
When you use
$string = mb_strcut($string, 6);
you can know for sure that strlen($string) <= 6. But no unicode characters will be truncated.
I hope my comment could finally be a simple explanation.
