How can the use of regular expressions be beneficial in parsing and extracting values from complex strings in PHP?

Regular expressions can be beneficial in parsing and extracting values from complex strings in PHP because they allow for pattern matching and searching within a string. This can be particularly useful when dealing with structured data or when trying to extract specific information from a larger text. By using regular expressions, you can define the pattern you are looking for and extract the desired values efficiently. 

// Example of using regular expressions to extract values from a complex string
$string = "Name: John Doe, Age: 30, Occupation: Developer";

// Define the pattern to match the name
$pattern = '/Name: (.*?),/';

// Use preg_match to extract the name from the string
preg_match($pattern, $string, $matches);

// Output the extracted name
echo "Name: " . $matches[1];
