How can PHP developers efficiently handle and modify strings that contain specific patterns or characters?

When dealing with strings that contain specific patterns or characters in PHP, developers can efficiently handle and modify them using regular expressions. Regular expressions allow for pattern matching and manipulation within strings, making it easier to extract or replace specific content. By using functions like preg_match() or preg_replace(), developers can target and modify strings based on defined patterns or characters. 

$string = "Hello, [Name]! How are you today?";
$pattern = "/\[Name\]/";
$replacement = "John";

$newString = preg_replace($pattern, $replacement, $string);

echo $newString;
