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

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.

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

)

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

   $characters = mb_split(",", $string); 
   print_r($characters); 
?>
