In the provided code example, what is the purpose of using the characters '%' and '?' as delimiters for splitting the string?

Using the characters '%' and '?' as delimiters for splitting the string allows for more flexibility in parsing the string. The '%' and '?' characters are less likely to appear in normal text, making them suitable choices for delimiters. By using these characters as delimiters, we can avoid potential conflicts with the actual content of the string being split. 

// Original code with '%' and '?' as delimiters
$str = "Hello%World?This%is?a%test";
$parts = preg_split("/[%?]/", $str);

print_r($parts);
