The mb_split() is an inbuilt PHP function that split the multibyte strings with help of the regular expression.

Syntax:

mb_split(pattern,string,limit): array|false

Parameters: This function accepts 3 parameters:

pattern: In this parameter, we define a regular expression that helps us to split a string.
string: This parameter defines a string that’s going to be split using by pattern parameter.
limit: This parameter is an optional parameter. This parameter defines the maximum limit of the split string.

Return value: If this function executes successfully then it will return an array otherwise it will return “false”.

Example 1: The following code demonstrates the mb_split() function.

PHP

<?php 
   print_r(mb_split('\s',"Hello neveropen")); 
?>

Output:

Array
(
   [0] => Hello
   [1] => neveropen
)

Example 2: The following code demonstrates the mb_split() function using a delimiter.

<?php    
   $string = "The,longest,sentence,in,English,is,also,awesome"; 
   $characters = mb_split(",", $string); 
   print_r($characters); 
?>

Output:

Array
(
    [0] => The
    [1] => longest
    [2] => sentence
