mb_strcut — Get part of string
Beschreibung
string
$string,int
$start,?int
$length = null,?string
$encoding = null): string
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.
Parameter-Liste
-
string -
The string being cut.
-
start -
If
startis non-negative, the returned string will start at thestart'th byte position instring, counting from zero. For instance, in the string 'abcdef', the byte at position0is 'a', the byte at position2is 'c', and so forth.If
startis negative, the returned string will start at thestart'th byte counting back from the end ofstring. However, if the magnitude of a negativestartis greater than the length of the string, the returned portion will start from the beginning ofstring. -
length -
Length in bytes. If omitted or
NULLis passed, extract all bytes to the end of the string.If
lengthis negative, the returned string will end at thelength'th byte counting back from the end ofstring. However, if the magnitude of a negativelengthis greater than the number of characters after thestartposition, an empty string will be returned. -
encoding -
Der Parameter
encodinglegt das Zeichenencoding fest. Wird er nicht übergeben so wird die interne Zeichenkodierung genutzt.
Rückgabewerte
mb_strcut() returns the portion of
string specified by the
start and
length parameters.
