What are the best practices for using regular expressions to parse formatted text in PHP?

Regular expressions can be a powerful tool for parsing formatted text in PHP. To effectively use regular expressions for this purpose, it is important to first understand the structure of the text you are trying to parse. You can then create a regex pattern that matches the desired text elements and use functions like preg_match() or preg_match_all() to extract the relevant information. 

// Example code snippet for parsing formatted text using regular expressions in PHP

$text = "Name: John Doe, Age: 30, Email: john.doe@example.com";

// Define a regex pattern to match the desired text elements
$pattern = '/Name: (.*?), Age: (\d+), Email: (.*?)$/';

// Use preg_match() to extract the information based on the pattern
if (preg_match($pattern, $text, $matches)) {
    $name = $matches[1];
    $age = $matches[2];
    $email = $matches[3];
    
    // Output the extracted information
    echo "Name: $name, Age: $age, Email: $email";
} else {
    echo "No match found.";
}
