Fatal error: Cannot redeclare class DB in C:\***\htdocs\smile\admin\function.php on line 5

so this is functions line 5 is class DB{

<?php 

require('vars.php');

class DB{
	
	function query($query){
		mysql_connect($mysqllocation,$mysqlusername,$mysqlpassword) or die('Connection Failed');
		mysql_select_db($mysqldatabase) or die("Unable to select database");
		mysql_query($query) or die('Query Error');
		mysql_close();
	}
	
	function row($query){
		$connect = mysql_connect($mysqllocation,$mysqlusername,$mysqlpassword);
		mysql_select_db($mysqldatabase, $connect);
		$result = mysql_query($query) or die(mysql_error());
		$row = mysql_fetch_array($result) or die(mysql_error());
		return $row;
	}
}


?>

I tried include_once vars in the functions itself and include vars in the function...

Now I've seen people using public vars... I don't get by the way... so am I calling my vars wrong because their just strings containing mysql data?


From what I understand using require halts the script causing a fatal error?
But when I comment it out I still get a fatal error.

My own fault I was using require instead of require once to pull the functions.
