PHP allows you to send e-mails directly from a script. The PHP mail() function is used to send emails from inside a script.
mail($to, $subject, $message, $headers);
As you can see above, the mail function has four parameters.
* $to – the recipients email address
* $subject – the subject of the email.
* $message – the email message to be sent.
* $headers – the header contains information such as the format of the email (plain text or HTML), senders name and email, reply to address, CC and BCC.

$headers = "From:" . $from;
