What are the differences in behavior when using the @ symbol to suppress errors in PHP functions like mail()?

When using the @ symbol to suppress errors in PHP functions like mail(), it means that any errors or warnings generated by the function will not be displayed to the user. This can make debugging more difficult as any issues with the function will not be immediately visible. It is generally not recommended to use the @ symbol to suppress errors, as it is better to handle errors properly in the code.

// Example of using the @ symbol to suppress errors in the mail() function
@mail($to, $subject, $message);
