How can regular expressions (RegEx) be used to effectively split a string in PHP?

Regular expressions (RegEx) can be used in PHP to effectively split a string by defining a pattern to match the delimiter between the substrings. By using the `preg_split()` function in PHP, we can split a string based on a regular expression pattern and store the substrings in an array. This allows for more flexibility in splitting strings compared to using simple string functions like `explode()`. 

$string = "Hello,World!This,is,a,test";
$pattern = '/[,.!]/'; // Define the pattern to split the string by commas, periods, or exclamation marks
$parts = preg_split($pattern, $string);

print_r($parts); // Output the array of substrings
