In what scenarios would it be recommended to use regular expressions over other methods for string manipulation in PHP?

Regular expressions are recommended for string manipulation in PHP when you need to perform complex pattern matching or search operations within a string. They are particularly useful when you need to find and replace specific patterns of text, extract certain data from a string, or validate input based on a specific pattern. 

$string = "Hello, my email is example@email.com";
$pattern = '/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/';
preg_match($pattern, $string, $matches);
$email = $matches[0];
echo $email; // Output: example@email.com
