What best practices should PHP developers follow to ensure smooth operation of their scripts, especially when dealing with mail sending functionality?

When sending emails in PHP, it's important to handle errors gracefully to ensure smooth operation of your scripts. One way to do this is by using try-catch blocks to catch any exceptions that may occur during the email sending process. By doing this, you can handle errors appropriately and prevent them from crashing your script. 

try {
    // Attempt to send the email
    // Your email sending code here
} catch (Exception $e) {
    // Handle any exceptions that occur during the email sending process
    echo 'An error occurred: ' . $e->getMessage();
}
