无法通过WAMP本地服务器phpmyadmin连接到数据库

Here is my code for connection to Database i.e. my Connection.php file.

<?php
$host="localhost";
$user="root";
$password="123456";
$database="database name";

$conn=mysql_connect($host,$user,$password);
mysql_select_db($database); 

if($conn){
   $mysqlError=FALSE;
}
else{
   echo "Unable to connect to Database"; $mysqlError=TRUE;
}
?>
