// Put in your variable values here.
$dbhost = "yourhost"; // usually localhost
$dbuser = "yourusername";
$dbpass = "yourpassword";
$dbname = "yourdb";
$sendto = "You ";
$sendfrom = "Automated Backup ";
$sendsubject = "Daily Mysql Backup";
$bodyofemail = "Here is the daily backup.";

// don't need to edit below this section 
$backupfile = $dbname . date("Y-m-d") . '.sql';
system("mysqldump -h $dbhost -u $dbuser -p$dbpass $dbname > $backupfile");
 
// Mail the file
//the includes here are for your PEAR extensions. Confirm PEAR is installed in your PHP.
 
    include('Mail.php');
    include('Mail/mime.php');
 
	$message = new Mail_mime();
	$text = "$bodyofemail";
	$message->setTXTBody($text);
	$message->AddAttachment($backupfile);
    	$body = $message->get();
        $extraheaders = array("From"=>"$sendfrom", "Subject"=>"$sendsubject");
        $headers = $message->headers($extraheaders);
    $mail = Mail::factory("mail");
    $mail->send("$sendto", $headers, $body);
 
// Delete the file from your server
unlink($backupfile);
