Stuck at Parse Error

Hello guys I am stuck at this error “Parse error: syntax error, unexpected ‘<’, expecting end of file in C:\laragon\www\farmer\config\config.php on line 4”

Here is my updated config.php

<?php include_once(''); <?php mysql_connect("localhost", "root", "newton2010") or die(mysql_error()); mysql_select_db("farmer") or die(mysql_error()); ?> <?Php //session_start(); $dbhost_name = "localhost"; $database = "farmer";// database name $username = "root"; // user name $password = "newton2010"; // password //////// Do not Edit below ///////// try { $dbo = new PDO('mysql:host=localhost;dbname='.$database, $username, $password); } catch (PDOException $e) { print "Error!: " . $e->getMessage() . "
"; die(); } ?>

Its been a while since I have messed with PHP but from what I remember you should have the <?php at the start of the file, then ?> at the end of the file

You can open and close multiple instances

<?php /*code here*/ ?>
<?php /*more code here*/ ?>

But you have multiple instances of the opening php tags: <?php but you are not closing them
