How can preg_split be utilized effectively in PHP for this specific regex parsing task?

To utilize preg_split effectively in PHP for this specific regex parsing task, we can use it to split a string into an array based on a regular expression pattern. This can be useful for breaking down a string into its individual components, such as separating words or numbers. 

```php
$string = "Hello, world! This is a test string 123";
$pattern = '/[\s,]+/';
$words = preg_split($pattern, $string);

print_r($words);
```

In this code snippet, we have a string containing words and numbers. We use preg_split with the pattern '/[\s,]+/' to split the string into an array based on spaces and commas. The resulting array will contain each word or number as a separate element.
