mb_str_splitGiven a multibyte string, return an array of its characters


mb_str_split ( string $string , int $length = 1 , string|null $encoding = null ) : array

This function will return an array of strings, it is a version of str_split() with support for encodings of variable character size as well as fixed-size encodings of 1,2 or 4 byte characters. If the length parameter is specified, the string is broken down into chunks of the specified length in characters (not bytes). The encoding parameter can be optionally specified and it is good practice to do so.



The string to split into characters or chunks.


If specified, each element of the returned array will be composed of multiple characters instead of a single character.


Der encoding Parameter legt das Zeichenencoding fest. Wird er nicht ├╝bergeben so wird die interne Zeichenkodierung genutzt.
