mb_strcut — Get part of 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.
str
The string being cut.
start
If start
is non-negative, the returned string
will start at the start
'th byte position in
str
, 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 str
.
length
Length in bytes. If omitted or NULL is passed, extract all bytes to the end of the string.
encoding
Der encoding
Parameter legt das Zeichenencoding fest. Wird er nicht übergeben so wird die interne Zeichenkodierung genutzt.
mb_strcut() returns the portion of
str
specified by the
start
and
length
parameters.

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