PHP 7.0.26 Released

mb_strcut

(PHP 4 >= 4.0.6, PHP 5)

mb_strcutGet part of string

Description

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

mb_strcut() performs equivalent operation as mb_substr() with different method. If start position is multi-byte character's second byte or larger, it starts from first byte of multi-byte character.

It subtracts string from str that is shorter than length AND character that is not part of multi-byte string or not being middle of shift sequence.

Parameters

str

The string being cut.

start

The position that begins the cut.

length

The string being decoded.

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.

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.

Here is an example with UTF8 characters, to see how the start and length arguments are working:

  $str_utf8 = utf8_encode("Déjà_vu");
  $str_utf8_0 = mb_strcut($str_utf8, 0, 4, "UTF-8"); // Déj
  $str_utf8_1 = mb_strcut($str_utf8, 1, 4, "UTF-8"); // éj
  $str_utf8_2 = mb_strcut($str_utf8, 2, 4, "UTF-8"); // éj
  $str_utf8_3 = mb_strcut($str_utf8, 3, 4, "UTF-8"); // jà_
  $str_utf8_4 = mb_strcut($str_utf8, 4, 4, "UTF-8"); // à_v

The string includes two special charaters, "é" and "à" internally coded with two bytes.
Note that a multibyte character is removed rather than kept in half at the end of the output.
Note also that the result is the same for a cut 1,4 and a cut 2,4 with this string.
