Are there any best practices or guidelines for using regular expressions effectively in PHP code?

Regular expressions can be a powerful tool in PHP for pattern matching and manipulation of strings. To use regular expressions effectively, it is important to follow best practices such as using the appropriate functions like preg_match() or preg_replace(), escaping special characters, and using anchors (^ and $) to match the beginning and end of a string. 

// Example of using preg_match to match a specific pattern in a string
$string = "Hello, World!";
if (preg_match("/^Hello/", $string)) {
    echo "String starts with 'Hello'";
} else {
    echo "String does not start with 'Hello'";
}
