What are some alternative approaches or best practices for achieving the desired output of splitting a string into incremental substrings in PHP?

When splitting a string into incremental substrings in PHP, one common approach is to use the `str_split()` function. This function allows you to specify the length of each substring. Another approach is to use a loop to iterate over the string and extract substrings of a fixed length. 

// Using str_split() function
$string = "HelloWorld";
$substring_length = 3;
$chunks = str_split($string, $substring_length);
print_r($chunks);

// Using a loop
$string = "HelloWorld";
$substring_length = 3;
$chunks = [];
for ($i = 0; $i < strlen($string); $i += $substring_length) {
    $chunks[] = substr($string, $i, $substring_length);
}
print_r($chunks);
