What steps can be taken to troubleshoot issues with the mail() function in PHP?

If the mail() function in PHP is not sending emails as expected, you can troubleshoot the issue by checking the spam folder, verifying the email address, and ensuring that the server's mail configuration is correct. Additionally, you can use the error reporting functions in PHP to identify any specific errors that may be occurring. 

// Example code snippet to troubleshoot mail() function issues
error_reporting(E_ALL);
ini_set('display_errors', 1);

$to = "recipient@example.com";
$subject = "Test Email";
$message = "This is a test email.";

$headers = "From: sender@example.com";

if (mail($to, $subject, $message, $headers)) {
    echo "Email sent successfully";
} else {
    echo "Email sending failed";
}
