What are the advantages of using preg_replace over str_replace for replacing characters in a string in PHP?

When replacing characters in a string in PHP, using preg_replace offers more flexibility and power compared to str_replace. preg_replace allows for the use of regular expressions, making it easier to target specific patterns or conditions for replacement. This can be particularly useful when dealing with complex or dynamic strings that require more advanced matching criteria. 

// Using preg_replace to replace characters in a string
$string = "Hello, World!";
$newString = preg_replace('/[aeiou]/', '*', $string);
echo $newString; // Output: H*ll*, W*rld!
