What are the potential benefits of using try/catch blocks in PHP functions like sending emails with PHPMailer?

When sending emails with PHPMailer, there may be potential issues such as network errors, SMTP server problems, or incorrect email addresses causing the email sending process to fail. To handle these potential errors gracefully and prevent the entire script from crashing, we can use try/catch blocks in PHP functions. By wrapping the email sending code in a try block and catching any exceptions that occur in the catch block, we can handle errors appropriately and provide feedback to the user. 

use PHPMailer\PHPMailer\Exception;
use PHPMailer\PHPMailer\PHPMailer;

try {
    $mail = new PHPMailer();
    // email sending code here
    $mail->send();
    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Email could not be sent. Error: ' . $mail->ErrorInfo;
}
