mb_str_split — Given 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.
string
The string to split into characters or chunks.
length
If specified, each element of the returned array will be composed of multiple characters instead of a single character.
encoding
The encoding parameter is the character encoding. If it is omitted or null, the internal character encoding value will be used.
A string specifying one of the supported encodings.
mb_str_split() returns an array of strings.
