Hello needed with silple php set up

Hi all,
im new to php so please be easy on me :slight_smile:
im trying to send an email from flash using php, but for some reason it wont work. Im testing locally to see if i can do this with this code.

// code used
<?php
mail(“didosh@wanadoo.fr”, $subject, $message, “From: PHPMailer
Reply-To: $from
X-Mailer: PHP/” . phpversion());
?>

// output
Warning: Failed to connect to mailserver, verify your “SMTP” setting in php.ini in c:\phpdev\www est\mail.php3 on line 2

i have no idea what "SMTP"is or how to find it even less about the php.ini file

any help would be greatful
