What are the potential pitfalls of using eregi_replace in PHP?

Using eregi_replace in PHP is not recommended as it is deprecated and has been removed in newer versions of PHP. It is better to use the preg_replace function with the 'i' modifier for case-insensitive matching. This will ensure compatibility with newer PHP versions and provide better performance. 

// Using preg_replace instead of eregi_replace
$newString = preg_replace('/pattern/i', 'replacement', $string);
