What are the potential pitfalls of using regular expressions (RegExp, Regex) for extracting data from strings in PHP?

One potential pitfall of using regular expressions for extracting data from strings in PHP is that they can be complex and difficult to maintain, especially for beginners. To solve this issue, consider using built-in PHP functions like `preg_match()` or `preg_match_all()` which provide a simpler and more readable way to extract data from strings. 

// Using preg_match() to extract data from a string
$string = "Hello, my email is example@email.com";
$pattern = '/\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b/';
preg_match($pattern, $string, $matches);
$email = $matches[0];
echo $email;
