Calling mail() function in PHP not working it returns 'failure' on local server. Can it work on local or I need to check mail on live server?

See more:

PHP

if(mail($to, $subject, $message, $headers)) {
echo json_encode(array('status' => 'success', 'message' => 'Your request has been recorded. Thank you.'));
} else {
$errorMessage="hello";
echo "alert('$errorMessage');";
echo json_encode(array('status' => 'failure', 'message' => 'Could not process your request. Please try again.'));
}

What I have tried:

i have tried it on local server and i don't know will it work on local server or not as i am new in php.
