What are the potential pitfalls when using preg_split in PHP for text manipulation?

One potential pitfall when using preg_split in PHP for text manipulation is that it may not handle certain special characters or patterns correctly, leading to unexpected results. To solve this issue, you can use the preg_quote function to escape any special characters before using preg_split. 

$text = "Hello, world! This is a test.";
$delimiter = "/[\s,]+/";
$escaped_delimiter = preg_quote($delimiter, '/');
$words = preg_split('/' . $escaped_delimiter . '/', $text);
print_r($words);
