How can the PREG_SPLIT_DELIM_CAPTURE flag in preg_split function help in capturing delimiters in PHP?

When using the preg_split function in PHP to split a string by a delimiter, the PREG_SPLIT_DELIM_CAPTURE flag can be used to include the delimiters in the resulting array. This can be useful when you need to capture both the delimiters and the substrings between them for further processing. 

```php
$string = "Hello,world!";
$parts = preg_split('/(\W)/', $string, -1, PREG_SPLIT_DELIM_CAPTURE);
print_r($parts);
```

In the example above, the string "Hello,world!" is split by non-word characters using the regex pattern (\W). The PREG_SPLIT_DELIM_CAPTURE flag is used to capture both the substrings and the delimiters in the resulting array $parts.
