Use the mail()
function.
You can see if your website supports it by testing with the following example:
<?
$to = "tester@example.com";
$from = "php@example.com";
$subject = "test php mail function";
$message = "this is a 2\n line message.";
if ($from) {
$headers .= "From: $from";
}
if (mail($to, $subject, $message, $headers)) {
print "mail sent successfully to $to";
}
else {
print "mail send failed!";
}
?>
