What are some best practices for using regular expressions in PHP to search for specific patterns in text?

Regular expressions are a powerful tool for searching and manipulating text in PHP. To search for specific patterns in text using regular expressions, it's important to follow some best practices. This includes using the preg_match() function to perform the search, escaping special characters in the pattern, and using capturing groups to extract specific parts of the matched text. 

$text = "The quick brown fox jumps over the lazy dog";
$pattern = '/\b(quick|lazy)\b/';

if (preg_match($pattern, $text, $matches)) {
    echo "Match found: " . $matches[0];
} else {
    echo "No match found";
}
