What is the difference between using "@mail" and "mail" functions in PHP for sending emails?

The main difference between using "@mail" and "mail" functions in PHP for sending emails is that the "@" symbol suppresses any errors or warnings that may occur during the email sending process. While using "@mail" can help avoid displaying errors to the user, it is generally not recommended as it can make debugging issues more challenging. It is better practice to use the "mail" function without the "@" symbol and handle any errors that may arise appropriately.

// Using the mail function without suppressing errors
$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.";
}
