Are there any specific PHP functions or libraries recommended for handling regex operations efficiently?

When handling regex operations in PHP, it is recommended to use the `preg_match()` function for matching patterns in strings efficiently. Additionally, using the `preg_match_all()` function can be useful for finding all occurrences of a pattern in a string. For more complex regex operations, the `preg_replace()` function can be used to replace patterns in strings. 

// Example of using preg_match() to match a pattern in a string
$string = "Hello, World!";
$pattern = "/\bHello\b/";
if (preg_match($pattern, $string)) {
    echo "Pattern found in the string.";
} else {
    echo "Pattern not found in the string.";
}
