What are the potential pitfalls of using regular expressions in PHP for text manipulation and how can they be avoided?

One potential pitfall of using regular expressions in PHP for text manipulation is that they can be complex and difficult to read, leading to errors and bugs in the code. To avoid this, it is important to properly comment and document the regular expressions used in the code. Additionally, using built-in PHP functions for text manipulation where possible can simplify the code and make it easier to maintain.

// Example of using built-in PHP functions for text manipulation instead of complex regular expressions
$text = "Hello, World!";
$reversedText = strrev($text);
echo $reversedText;
