What steps can be taken to troubleshoot and debug issues with the PHP mail function, such as not receiving the expected sender information?

Issue: If you are not receiving the expected sender information when using the PHP mail function, it could be due to incorrect headers being set or a misconfiguration in your server settings. Fix: To ensure that the sender information is correctly set in the email headers, you can use the "From" header in the mail function. Make sure to include the sender's email address and name in the header. Here is an example code snippet: 

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

$headers = "From: Sender Name <sender@example.com>\r\n";
$headers .= "Reply-To: sender@example.com\r\n";

mail($to, $subject, $message, $headers);
