What are the advantages and disadvantages of using explode() versus mb_split() for string manipulation in PHP?

When manipulating strings in PHP, the explode() function is commonly used to split a string into an array based on a specified delimiter. However, if you are working with multibyte characters (such as those in languages like Chinese or Japanese), using mb_split() is recommended as it properly handles these characters. The disadvantage of mb_split() is that it is slightly slower than explode() due to the additional processing required for multibyte characters.

// Using explode() to split a string
$string = "Hello,World";
$array = explode(",", $string);
print_r($array);

// Using mb_split() to split a string with multibyte characters
$string = "你好,世界";
$array = mb_split(",", $string);
print_r($array);
