PHP mb_split() Function

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
   print_r(mb_split('\s',"Hello GeeksforGeeks"));
?>

Output:

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

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);
?>
