What are some common pitfalls to avoid when using regular expressions in PHP for text manipulation?

One common pitfall to avoid when using regular expressions in PHP for text manipulation is using inefficient patterns that can lead to performance issues, especially when dealing with large amounts of data. To solve this, it's important to optimize your regular expressions by making them as specific as possible and avoiding unnecessary complexity. 

// Inefficient regular expression pattern
$pattern = '/(foo|bar)+/';

// Optimized regular expression pattern
$pattern = '/(?:foo|bar)+/';
