How can regular expressions be utilized to parse and extract specific data from preformatted text in PHP?

Regular expressions can be utilized in PHP to parse and extract specific data from preformatted text by defining patterns that match the desired data. By using functions like preg_match() or preg_match_all(), you can search the text for the defined pattern and extract the data accordingly. This allows for efficient and flexible extraction of specific information from text. 

// Sample preformatted text
$text = "Name: John Doe, Age: 30, Occupation: Developer";

// Define a regular expression pattern to extract the name
$pattern = '/Name: ([\w\s]+)/';

// Use preg_match() to extract the name
if (preg_match($pattern, $text, $matches)) {
    $name = $matches[1];
    echo "Name: $name";
}
