What best practices should PHP developers follow when working with regular expressions to avoid errors and achieve accurate results, as highlighted in the forum discussion?

When working with regular expressions in PHP, developers should ensure they are using the correct syntax and escaping special characters properly. It's important to thoroughly test the regular expressions to avoid errors and achieve accurate results. Additionally, using built-in PHP functions like preg_match() or preg_replace() can help simplify the process and make the code more readable. 

// Example of using preg_match to validate an email address
$email = "example@example.com";
if (preg_match("/^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$/", $email)) {
    echo "Valid email address";
} else {
    echo "Invalid email address";
}
