What are some potential pitfalls when using preg_split in PHP for string manipulation?

One potential pitfall when using preg_split in PHP for string manipulation is that it may not handle certain special characters or regex patterns as expected, leading to unexpected results. To avoid this, it's important to carefully consider the regex pattern used and test it with various input strings to ensure it behaves as intended. 

// Example of using preg_split with a carefully crafted regex pattern to avoid pitfalls
$string = "Hello, world! This is a test.";
$words = preg_split('/\s+/', $string);

print_r($words);
