mb_strcut

(PHP 4 >= 4.0.6, PHP 5)

mb_strcutGet part of string

Description

string mb_strcut ( string $str , int $start [, int $length = NULL [, string $encoding = mb_internal_encoding() ]] )

mb_strcut() extracts a substring from a string similarly to mb_substr(), but operates on bytes instead of characters. If the cut position happens to be between two bytes of a multi-byte character, the cut is performed starting from the first byte of that character. This is also the difference to the substr() function, which would simply cut the string between the bytes and thus result in a malformed byte sequence.

Parameters

str

The string being cut.

start

If start is non-negative, the returned string will start at the start'th byte position in string, counting from zero. For instance, in the string 'abcdef', the byte at position 0 is 'a', the byte at position 2 is 'c', and so forth.

If start is negative, the returned string will start at the start'th byte from the end of string.

length

Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string.

encoding

The encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.

Return Values

mb_strcut() returns the portion of str specified by the start and length parameters.

Changelog

Version Description
5.4.8 Passing NULL as length extracts all bytes to the end of the string. Prior to this version NULL was treated the same as 0.

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

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.
